How to add arbitrary files into sandbox?

[eadwu]

For some reason I can't seem to do it, I've tried mkosi.sandbox, mkosi.skeleton, mkosi.extras and the respective configuration options.

cannot open file: (2) - No such file or directory [/etc/pki/rpm-gpg/RPM-GPG-KEY-openzfs-fedora-41]

I've also tried copying the symlink source as well but no dice.

Please open an issue and add all the necessary information, run with --debug, and preferably provide a small example that reproduces the problem.

I found the issue, ToolTree=default has some weird interactions, I'm not sure how to fix, but I'll wait for perhaps the next release since downgrading to Fedora 41 won't work with ParticleOS before continuing.

Commenting out ToolTree makes it show in mkosi -f sandbox -- bash while ToolTree=default wipes it out.

ToolsTreeSandboxTrees doesn't seem to work with it.

Hackfix by injecting it into the mkosi.tools/ directory.
