Is NixOS Reproducible?, the minimal ISO is "1671 out of 1683 (99.76%) paths in the minimal installation image are reproducible!", from Generated at 2021-03-09 05:30:36.667870816 UTC from https://github.com/grahamc/r13y.com. Related: How to build a minimal example that replicate an minimal example of "It is possible there is nondeterminism in a package source, waiting for some specific circumstance." Are there some known impurities in builds in NixOS?

You Can't Unit Test C, Right?, start=760&end=801

libc is a very base system library, it’s not yet another library you can simply install along with others. Adding support for glibc would basically mean supporting another platform. The cost of this is too high. Also it doesn’t make much sense; Alpine with glibc would not be Alpine anymore! Alpine’s “motto” is: small, simply and secure. You can’t get this with glibc. https://github.com/gliderlabs/docker-alpine/issues/11#issuecomment-237842562

No! To the following:

So basically, if you need OracleJDK, you'll have to use one of the "standard" configurations for Java (eg use windows or oracle linux). If you need something else you'll have to hire JES. https://github.com/gliderlabs/docker-alpine/issues/11#issuecomment-255118537

Nix solves this problem!

"Most cross-compatible platform", they say...

The only exit would be a thin glibc facade bound to musl. And maybe this would be a kick for musl usage too.

Now we just need social engineering to convince a crazy guy for doing this. https://github.com/gliderlabs/docker-alpine/issues/11#issuecomment-255500590

Is this reproducible in some way? If so, can you try... https://github.com/containers/podman/issues/3761#issuecomment-519627655

They are incompatible with themselves. By "incompatible" I mean that a binary compiled under alpine is linked against the musl library, not against glibc. https://stackoverflow.com/a/59376077

Unofficial, but well reasoned answer:

SELinux is a PITA to use. Amazon Linux is designed to help people get started quickly. AWS wants you to have as few issues getting your app or service deployed in the cloud because; the idea is that it's like crack - one taste and you'll be back. You'll grow and want to deploy more stuff on AWS. The point is by the time you really need SELinux you're either capable of configuring it yourself or have an operations team that can make it a reality.

Also throw me in the bucket that thinks SELinux is overkill in a lot cases.

Is there an official answer on why SELinux isn't installed on official Amazon Linux AMIs?

Why is what we did at Dartmouth 50 years ago so great? Well... Let me think about it a second. Computing was coming into its own. But in all of the other projects that were undertaken by industry and by universities, the target was research and development of computing ideas and so forth. Whereas, here at Dartmouth, we had a crazy idea that our undergraduate students who are not going to be technically employed later on, social science and humanity students, should learn how to use the computer. Complete nutty idea. Birth of BASIC

Scientific truth is based on facts. Philosophy, religion, feelings, and prejudice have nothing to do with science. Only facts matter. Verified, reproducible facts are the bedrock of scientific truth. The facts are used to construct theories which describe the detailed relations among large numbers of facts and their origin from common roots. Each element of a theory corresponds to some part of nature and, in this sense, scientific theories describe nature.

Our only supported format is a compressed tarfile. If you really feel the need for .rpm or .deb versions, other parties (eg, Debian, SuSE) provide them (note that we can't answer questions on ATLAS installed in this way, however, since we don't know much about them). ATLAS provided by third parties may not be as up-to-date, or may run slower than compiled ATLAS (eg., some companies compile only a couple of x86 libraries, so that they would use the same library for the P4 and P4E chips, even though ATLAS should tune itself separately to all the x86 variants for maximal performance). Can I get ATLAS in rpm or .deb or some other format?

Another motivation to enforce the sandboxing is that we could get rid of the nixbld\d+ users. Each sandbox gets it's own pid namespace so they could all run with the same uid/gid. That would be great to limit the footprint nix has on non-nixos systems. https://github.com/NixOS/nix/issues/179#issuecomment-410318874 https://github.com/NixOS/nix/issues/179#issuecomment-435359202

Packaging TeX Live - the challenge of multi-platform support - Norbert Preining | PackagingCon 2021 > I was thinking about getting into writing it in Lua. Why because there is TeX Lua this is what uh one one engine one core engine now it is a taking the operator with Lua built in so you have a Lua interpreter also with the TeX integrator so that would be because we don't it's automatically we have a language where we can write but rewriting everything in Lua is a huge, work i don't want to do at the moment. What i would like to see is a better integration or interaction of TeXLive manager with distribution so this is quite i mean i'm also packaging for for Debian so i know what this means but it is so we have this user mode but it's not optimal it would be better to have a better interaction with these distributions then what is also a huge problem is sounds trivial but actually this is downloading lots of files we have um as i said we have three to four container per package times four thousand so it's twelve thousand files that author get downloaded for for an installation and to get this working somehow uniformly well you don't want to have code bars for everything across all platforms is a pain so we use lv LWP to get a stable connection and keep them up but it falls back to curl and the wget and i just mentioned certificates because it just popped up again i mean the let's encrypt ISRG Root X1 problem is still beating around so um yeah it's surprisingly difficult to get this right. Then CTAN as i mentioned before so i wish always and i hope but it will not change anymore for streak the rules i mean like CRAN has extremistic rules of the format of what is uploaded so that is something that would be really helpful for getting um distributing because they could directly install from sita like CRAN the ground manager in starts directly from agreement this is this is something we cannot do at the moment and i mean something because it was discussed here reuse of some universal package manager would be nice but **i haven't seen any of the package managers being being able to run on on the set of systems we are supporting even the reduced set of systems we are putting on to the DVD**.

Why why should you care about understanding your build? There's several reasons first and foremost is you want to have a fine-grained understanding what gets in your binary and you would say well of course I know that's my code I know exactly what gets built and it also pretty much until you have more than one CN header file now think about something like wheeled building a full Android device that means a whole stack from the kernel app this build typically involves multiple language compilers some people binaries scripts there's about four hundred thousand steps which are executed when you build another iDevice roughly that gives you a bit of an idea of the the complexity of the problem and that scale this is no longer fully deterministic now even if you don't do system programming's but do application level programming you create two node package talking about JavaScript and you say npm install and well guess what you have now 200 or 300 dependencies that were installed from left and right and that's only go large bill orbit like magic we know that work eventually they do most of the time they do but it's really hard to understand exactly what happens especially like in this case of NPM or maven or application and language specific package managers things are faction provision at Build time so they come from the network I remember long From: Debug your build by tracing and reversing stracing your build from sources to binaries, start=78&end=283

NixOS differs from something like Ansible in that it’s inherently declarative, through and through. If you remove the services.sshd.enable = true; line from your configuration, NixOS will tear down the OpenSSH server upon a rebuild. It’ll be as if it was never there (subtracting any leftover data), because there isn’t a practical difference between installing NixOS for the first time and building it again. Ansible has the notion of “idempotency”, but Nix (and NixOS) is idempotent by nature. https://www.slice.zone/blog/nix-in-practice

Filesystem Hierarchy Standard (FHS)

In particular, in our own version of the system, there is a directory "/usr" which contains all user's directories, and which is stored on a relatively large, but slow moving head disk, while the othe files are on the fast but small fixed-head disk. https://www.bell-labs.com/usr/dmr/www/notes.html 15 March, 1972

Understanding the bin, sbin, usr/bin, usr/sbin Split, By ROB LANDLEY, 2002?

Tutorial: Building the Simplest Possible Linux System - Rob Landley, se-instruments.com, start=4921&end=5023

The real reason we kept it is tradition. The execuse [sic] is that the root partition contains early boot stuff and /usr may get mounted later, but these days we use initial ramdisks (initrd and initramfs) to handle that sort of thing. The version skew issues of actually trying to mix and match different versions of /lib/libc.so. living on a local hard drive with a /usr/bin/ from the network mount are not pretty.

I.E. The seperation is just a historical relic, and I've consolidated it in the name of simplicity.

The one bit where this can cause a problem is merging /lib with /usr/lib, which means that the same library can show up in the search path twice, and when that happens binutils gets confused and bloats the resulting executables. (They become as big as statically linked, but still refuse to run without opening the shared libraries.) This is really a bug in either binutils or collect2, and has probably been fixed since I first noticed it. In any case, the proper fix is to take /lib out of the binutils search path, which we do. The symlink is left there in case somebody's using dlopen, and for "standards compliance".

On a related note, there's no reason for "/opt". [ ... ] Then Linux distributors wanted a place to install optional packages, and they had /bin, /usr/bin, and /usr/local/bin to choose from, but the problem with each of those is that they were already in use and thus might be cluttered by who knows what. So a new directory was created, /opt, for "optional" packages like firefox or open office.

It's only a matter of time before somebody suggests /opt/local, and I'm not humoring this. Executables for everybody go in /usr/bin, ones usable only by root go in /usr/sbin. There's no /usr/local or /opt. /bin and /sbin are symlinks to the corresponding /usr directories, but there's no reason to put them in the $PATH. https://busybox.net/%7Elandley/firmware/design.html

And almost 2 decades later:

It’s just too bad that no one actually cares about the FHS, and places their files wherever they want. Not only do different operating systems use different implementations of the FHS, but even different Linux distributions use different implementations. On top of that, the standard itself isn’t strict, and allows for exceptions to its own rules (X11R6 being placed in /usr, anyone?). What good is a standard nobody adheres to? Why Do We Hold on to the FHS? 2009

I just uploaded a new version of systemd into F15, which establishes a directory /run in the root directory. Most likely you'll sooner or later stumble over it, so here's an explanation what this is and why this is. What's this /run directory doing on my system and where does it come from?, Lennart Poettering, Wed, 30 Mar 2011 04:55:27 -0700

Since 1993, the Filesystem Hierarchy Standard (HS) [1] has been the guideline for Unix-like directory structures. It requires the root directory partition to contain all the files the system needs for booting and mounting additional partitions.

This results in 14 directories or symbolic links to them: /bin, /boot, /dev, /etc, /lib, /media, /mnt, /opt, /run, /sbin, /srv, /tmp, /usr, and /var. Only the /opt, /usr, and /var folders can be located on other partitions. In addition, FHS considers the home directory to be optional, along with /root, /lib32, and /lib64.

In 2015, FHS was integrated into the Linux Standard Base (LSB). FHS is now maintained under the umbrella of the Linux Foundation.

Starting in 2012, several distributions have chosen to merge the /usr directories [2], thus modifying the FHS (and are therefore no longer LSB-compliant). Starting with Debian 10 Buster, Debian has now joined the /usr merge ranks. https://www.linux-magazine.com/Issues/2019/228/Debian-usr-Merge

In my opinion it is "insane", but we can agree in disagree:

Can someone describe a scenario where this (name of the binary not clearly indicating it's related postgres) causes issues in practice? On my system, there are ~1400 binaries in /usr/bin, and for the vast majority of them it's rather unclear where do they come from. https://lwn.net/Articles/784508/ https://www.linux-magazine.com/Issues/2019/228/Debian-usr-Merge/(offset)/3#article_i6

A second attempt to re-enable /usr merge by default happened in June 2018, with debootstrap version 1.0.102. Since June 25, 2018, new default installations of Debian testing from the "daily" builds of the install CD have a merged /usr, and that has not been reverted so far.

Happy ending? Not so fast ... [ ... ] Problems with R [ ... ] On November 20, the change was reverted — build daemon chroots were recreated without a merged /usr. https://lwn.net/Articles/773342/

The gist is that neovim is just a C project, therefore doesn't link against C++. However, many plugins do use C++. And when the > plugins are downloaded as pre-compiled binaries, there was no previous loading of C++ libraries and no good "convention" on where to find them. This wouldn't be an issue on FHS systems, as the library in question libstdc++.so.6 is likely to exist.

Ultimately, it's an anti-pattern to try and distribute binaries outside of a system-compatible package manager. The issue of C++ abi is just waiting to blow off someone's foot. It's "works on my computer today", tomorrow it could be "can't run any C++ application". Refs.:

As in FHS systems, we make some assumptions regarding our system which includes that all the libraries will be in /lib or relevant directories. It’s, then, easier to fix the issue.

In FHS standardized / compliant Linux distributions it can be easily solved by installing the relevant library’s package. Refs.:

How did the "Slackware has no package management" myth originate?

I think the definition of package management just came to include dependency resolution. So what was perfectly acceptable package management one day became an obvious lack of "real" package management the next. [...]

What people refer to as "package management" now includes dependency checking.

You can argue that isn't the classic usage of the term, but people have decided that a "package manager" should include dependency resolution; like it or not. https://www.reddit.com/r/slackware/comments/24vo9e/how_did_the_slackware_has_no_package_management/

Unfortunately nothing is working, and it’s really worrying that such a simple task is so complicated and error prone on nixos :confused: https://discourse.nixos.org/t/how-to-install-a-specific-version-of-a-package-from-my-configuration-nix/18057/8

In fairness, this is not a simple task. It’s actively impossible to do on any other Linux distro, specifically because of the things you’re running into (i.e., no guarantee of backwards compatibility between distro versions).

You can always download a binary version of the package and patchelf it, if that is the “simple” you’re looking for.

Unfortunately, I think in this case what you’re trying to achieve is very difficult without a downstream package, or some active upstream maintenance - it isn’t always, but packages that don’t build easily or change frequently are subject to issues like this. https://discourse.nixos.org/t/how-to-install-a-specific-version-of-a-package-from-my-configuration-nix/18057/3
