Hi,
I'm trying to configure 'nix-worker --daemon' to run in chroot.
nix.conf:
build-users-group = nixbld
build-use-chroot = true
build-chroot-dirs = /dev /proc /bin
'/nix/store' is owned by root. [1]

Is /bin/sh a symlink? If it is, its target has to be in one of the
directories listed in ‘build-chroot-dirs’.
But more importantly, /bin/sh is likely to be a dynamically-linked
executable, linked against stuff from /lib, which is not in
‘build-chroot-dirs’. Thus, it won’t run in the chroot.
An option is to replace /bin/sh by the statically-linked Bash that’s in
distro/packages/bootstrap/*-linux/bash.
Another one, which I think we’ll do, is to change gnu-build-system.scm
to either run (system* "/path/to/our/bash" "./configure" ...), or call
‘patch-shebangs’ on ‘configure’.
HTH,
Ludo’.

Hi,
I'm getting the same error with the following command:
# ./pre-inst-env guix-daemon --build-users-group=nixbld -C 0

> directories listed in ‘build-chroot-dirs’.
Yes. It points to bash, which is in '/bin'.

Same error.

I don't know how to change the former, but I've tried the latter.
gnu-build-system.scm:
(phases set-paths unpack patch patch-shebangs configure build check
install strip)
AFAICT, it changed the build order, but the same error appeared
anyway.

The following works.
nix.conf:
build-users-group = nixbld
build-use-chroot = true
build-chroot-dirs = /dev /proc /bin /lib
Does it make sense? Will it help to catch impurities?
'attr' failed with the following backtrace, but 'hello' and 'wget' succeeded.

OK. Can you copy/paste the actual error, because I’m losing track. ;-)

I actually made this change I had in mind in commit d008415, in the
‘core-updates’ branch.
Currently many packages can be built in ‘core-updates’ in a chroot
without /bin. The only thing remaining to be fixed is execv* in glibc:
http://sourceware.org/ml/libc-alpha/2012-12/msg00311.html .

(Note that guix-daemon does *not* read nix.conf.)
Adding /bin and /lib means that many binaries beyond /bin/sh are leaked
into the build environment, which is workable, but not great.
If we can manage to build in chroots without /bin at all, that’ll be best.
If we cannot, then we’ll have to do that.

Again that’s because /bin/sh is either missing from the chroot, or it’s
there but it’s a symlink whose target is missing, or it’s a
dynamically-linked binary and some of its requirements are missing.
Just try ‘ldd /bin/sh’. Everything listed there should be in the chroot.

That’s because hydra.nixos.org runs NixOS; on NixOS /bin/sh is a symlink
to /nix/store/xxx-bash/bin/sh, and the chroot is setup with all the
dependencies of that path added to ‘build-chroot-dirs’.
Thanks,
Ludo’.

I was talking about this error. [1]

Yeah, got it.
First I tried to use 'nix-worker --daemon'.
nix.conf:
build-users-group = nixbld
build-use-chroot = true
build-chroot-dirs = /dev /proc /bin
I copied our 'bash' to '/bin/sh', ran './pre-inst-env
guix-build -K attr', and it succeeded.
Then I tried
'./pre-inst-env guix-daemon --build-users-group=nixbld -C 0 &'.
This error [1] appeared again.

By default /bin is not in the chroot. So you have to run (using, again,
a newly-added option):
guix-daemon --build-users-group=nixbld --chroot-directory=/bin
(There can be several --chroot-directory options.)
Thanks,
Ludo’.
