What are you trying to do specifically? Do you have an example I can look at?

I packaged it just fine, but the resulting program fails with

Can't exec "/bin/sh": No such file or directory at /nix/store/yc09sxq40aaai2141cv1d32c7wflh90c-equivs-2.3.1/bin/equivs-build line 54.

Here's something you can drop in flake.nix and try building with nix build -L .#:

{
  outputs = { self, nixpkgs }:
    let
      pkgs = import nixpkgs { system = "x86_64-linux"; };
    in {
      packages.x86_64-linux.default = pkgs.runCommand "foo" {
        nativeBuildInputs = [pkgs.perlPackages.perl];
      } ''
        ls -l /bin/sh || :
        perl -e 'system("echo bash version \$BASH_VERSION") == 0 or die "system failed: $!"'
      '';
    };
}

Without a working /bin/sh in my sandbox (check the nix-daemon sandbox-paths setting), I get:

$ nix build -L .#
foo> ls: cannot access '/bin/sh': No such file or directory
foo> system failed: No such file or directory at -e line 1.
error: builder for '/nix/store/4pvz9fm4lsg5x0b0hcnf19wpvvkkg4cr-foo.drv' failed with exit code 2;
       last 2 log lines:
       > ls: cannot access '/bin/sh': No such file or directory
       > system failed: No such file or directory at -e line 1.
       For full logs, run 'nix log /nix/store/4pvz9fm4lsg5x0b0hcnf19wpvvkkg4cr-foo.drv'.

hi, i'm back again hoping to get some guidance. i'm troubleshooting this issue: https://github.com/NixOS/nixpkgs/issues/271880

from what i can discern, slimserver seems to be failing to load the files from lib/perl5/site_perl/5.38.2/x86_64-linux-thread-multi/auto, in this case specifically for Audio-Scan. They much with the autoloading of modules in their bootstrap, injecting the vendored modules (which we've mostly dropped) https://github.com/Logitech/slimserver/blob/6ef52be5f61d9f5017a493ddb5ea675854b9772e/Slim/bootstrap.pm#L133

In reply to @stigo:matrix.org
My thinking at the time was to look at why slimserver needs specific versions of vendored packages (for example DBI), and try to patch slimserver to be able to use the latest ones. I havent looked at the issue yet tho, can do tomorrow eve unless someone beats me to it :)

In reply to @adam:robins.wtf
Should `auto` be loaded from automatically?
