Hi Guix Team,
Is there any plan to include "proot-static" with Guix Binary releases ?
My request is motivated by the fact i'm looking for a way to use/install Guix only with the bin release on a non-privileged environnement (HPC, non root user) without the need to use guix pack on another computer to create a "pack" only for this package for every architecture i would like to install Guix on.
This way, if namespaces are not available, we could use Guix with Proot without any more efforts.
Best regards,

Good question!

Indeed. (I assume you read
<https://guix-hpc.bordeaux.inria.fr/blog/2017/10/using-guix-without-being-root/>,
which is about running software from a pack, rather than running Guix
itself. Pjotr has a very good writeup on this topic, which includes
running Guix itself under PRoot:
<https://gitlab.com/pjotrp/guix-notes/blob/master/GUIX-NO-ROOT.org>.)
Including proot-static makes a lot of sense and easily done (it adds
3 MiB to the result.) We’d need to document it properly though,
probably with a new section under “Setting Up the Daemon”. We could
mention user namespaces as another option for non-root users.
Thoughts? Ricardo?

I think with 3Mb only we should do it.
We also need a channels mechanism. My itch is getting so large I may
actually start coding at some point ;)

Currently proot only build successfully on x86_64 and i686, so that is
something we would need to fix first.

Indeed, that’s a bummer.

Are you sure that is not just a limitation of the qemu transparent emulation?
I examined the test failures in proot-static and it's clear that qemu will have
some trouble finding out what one wants to happen:

>#include <stdlib.h> /* exit(3), */

Now, qemu transparent emulation still picks up, but then the missing
argv[0] will be a problem.
And indeed,
$ guix environment -s armhf-linux proot-static
[...]
[env]$ ./test-25069c12
qemu: no user program specified

Oh, I hadn’t thought about that.

Are you saying that /proc/self/exe is incorrect when using binfmt_misc?
D’oh!
--8<---------------cut here---------------start------------->8---
$ uname -m
x86_64
$ guix environment --ad-hoc coreutils -s armhf-linux
[env]$ uname -m
armv7l
[env]$ sleep 100 &
[1] 2410
[env]$ ls -l /proc/2410/exe
lrwxrwxrwx 1 ludo users 0 Mar 25 09:55 /proc/2410/exe -> /gnu/store/6ar48khay4zd435cvkv4bgf1jih7jimq-qemu-3.1.0/bin/qemu-arm
--8<---------------cut here---------------end--------------->8---
So that could well be a problem (potentially in other packages as well;
I didn’t expect /proc/self/exe to be “wrong”.)
We’ll have to check what happens on berlin though, because there we
build on the bare metal.
Thanks,
Ludo’.

I think it’s fine to include it. I wouldn’t know how to document its
use, though. Is the idea to run the daemon under proot?

Documented on my page guix-no-root.
