Need a list of commands in provider rescue console

[bretton]

The depenguinme.sh script can only work with the binaries that exist in the linux rescue environment, or with statically-compiled binaries that are downloaded.

It would be useful to have a list of binaries available /bin and /usr/bin and /usr/sbin etc from a rescue console such as Hetzner.

For example: Is it possible to create an ISO file in the rescue system? Does mkisofs exist by default or do we need a statically-compiled copy?

I can look into this soonish (just need to reboot one of the machines…).

Depending on available memory on servers, using apt-get install could also be an option, at least for smaller tools. Ideally, users won’t have to download any binaries from untrusted locations.

Cool beans, specifically need the following available, possibly others:

• /usr/bin/genisoimage
• /usr/bin/mkisofs

genisoimage and mkisofs (both part of the same package) are not installed by default, but installing them with apt-get is no problem at all, only require 1.6MB.

Based on these results, I would suggest to simply apt-get install the required bits (at least by default), as this would make sure that they come from an authoritative source (debian or hetzner repos) and are recent. Don't forget to run apt-get update once though.

Thanks! I've include the apt-get update and apt-get install mkisofs but not the qemu one yet.

I'm using custom uefi.bin for bios as per original posts in forums, and it will need testing to see if it works on Hetzner hosts with qemu from packages.

I think this can be closed now
