Describe the bug

When running the CI for my infra on podman, building lix fails at the installCheckPhase, with 12 failed checks.
Some of the failures are due to #157, but other are not:

86/154 lix:installcheck / functional-build-remote-content-addressed-floating          FAIL             0.39s   exit status 1
94/154 lix:installcheck / functional-build-remote-trustless-should-fail-0             FAIL             0.28s   exit status 100
107/154 lix:installcheck / functional-linux-sandbox                                    FAIL             0.25s   exit status 100
108/154 lix:installcheck / functional-supplementary-groups                             FAIL             0.28s   exit status 1
112/154 lix:installcheck / functional-shell                                            FAIL             0.63s   exit status 1
145/154 lix:installcheck / functional-nested-sandboxing                                FAIL             0.29s   exit status 1

I added the logs of these tests.

Steps To Reproduce

I agree that these error may not be easy to reproduce, given the complicated build process, it uses https://git.hubrecht.ovh/hubrecht/nix-modules/src/branch/main/services/forgejo-nix-runners/default.nix to run nix builds inside podman containers through forgejo actions...

Expected behavior

The tests to not fail

`nix --version` output

Additional context

Add any other context about the problem here.

So when it ssh's into localhost it then can't find busybox? wat

worth noting that ssh to localhost does not invoke ssh, instead it invokes bash -c. perhaps that interacts somehow.

Then in xonsh:

source ./sandbox.xsh ; build_image() ; run_podman()

Inside the container:

rm -rf build
nix develop .#native-clangStdenvPackages
just setup
just install
just test

This will explode in the same way as described above, I think. FWIW: your container setup is pretty busted and has bad perms on /tmp among other things.

There are complaints that /nix/store/l85ia9bwz4v0k09v716sx2f2cjar3jvp-busybox doesn't exist. This is copied from /nix/store/svsnsvyz3h7vxkcssalms7c5y4pq5n5h-busybox-static-x86_64-unknown-linux-musl-1.36.1/bin/busybox via the $busybox variable in the tests, which becomes --arg busybox /nix/store/svsnsvyz3h7vxkcssalms7c5y4pq5n5h-busybox-static-x86_64-unknown-linux-musl-1.36.1/bin/busybox, which is a path literal that causes that copy.

I don't think that that copy is busted, so maybe it got deleted????? idk!!!

I don't know why the copy doesn't appear to actually happen.

I've attached test logs from this container. You can view the junit one with https://github.com/lukejpreston/xunit-viewer/ which is slightly nicer.

At this point I don't have many more spoons to fight this issue.
