Merry holidays everybody!

I am trying again to build nix using my custom storage and it is failing again. The build process goes smoothly with this configure.

./configure
         --enable-gc
         --with-store-dir="/cvmfs/packages.redbeardlab.com/nix/store"
         --localstatedir="/cvmfs/packages.redbeardlab.com/nix/state"
         --prefix="/cvmfs/packages.redbeardlab.com/nix/installation"
make 
make install

Then I proceed to add nixpkgs to the channel list.

nix-channel --add https://nixos.org/channels/nixpkgs-unstable

And finally I try to update the list.

$ nix-channel --update
unpacking channels...
while setting up the build environment: executing '/bin/bash': No such file or directory

error: program '/cvmfs/packages.redbeardlab.com/nix/installation/bin/nix-env' failed with exit code 100

It is me doing something wrong? Do I miss some step?

Cheers,

Also note that this is the very first --update

zimbatm commented 4 years ago

What OS is Nix being installed into?
Does /bin/bash exist on that OS?
Is user-namespaces available in that machine?

It seems to me that we are bind-mounting the whole filesystem into \cvmfs/packages.redbeardlab.com/nix/store/jwb38bww36svjgp4blki0f8zdmq482r0-nixpkgs-20.03pre206486.a8fc904c7c0.drv.chroot

But I don't see the /bin directory being mounted.

So it would make completely sense that /bin/bash does not appear to exists.

Am I wrong?

Given https://github.com/NixOS/nix/issues/3299#event-2920009651 write a test and make sure it fails.

Even the latest version 2.3.2 results in exactly the same problem.

The problem is very well reproducible, but my skills and time are limited. Am I the only one who has this problem?

Is there a reason you are using a different store dir as well as a different installation prefix? Given this setup you'll most likely need to either configure the build better (perhaps --with-sandbox-shell=?) or change sandbox-paths appropriatly in nix.conf.

Alternatively, instead of an impure build I would recommend you try building a customized nix from nixpkgs instead. That's more likely to have everything isolated properly and has the advantage of having things like builtins.storePath work more like expected.

with import <nixpkgs> {};
nix.override {
  storeDir = "\cvmfs/packages.redbeardlab.com/nix/store";
  stateDir = "\cvmfs/packages.redbeardlab.com/nix/var/nix";
  confDir = "\cvmfs/packages.redbeardlab.com/etc";
}
