Failure to call useradd/groupadd in akmods prein script (NVIDIA)

[abustany]

Describe the bug When trying to update/install new packages on my Silverblue install (currently on 36.20220716.0), rpm-ostree fails at the "Running pre scripts" step. I'm not sure if a specific akmod package fails, or if it's akmods itself.

Complete log:

I managed to rebase on top of 410f3504fd7f73e3c2a1b1fc070e605c82531a1d35868b3911e94d0e7f996436 by uninstalling the kmod-wl package, upgrading (hitting #322 on the way :sweat_smile:), and reinstalling akmod-wl, but then the issue reappears: the prein script from that package prevents upgrading the system or layering any other package.

We're having this issue in Fedora CoreOS too but we haven't found the solution yet: https://github.com/coreos/fedora-coreos-tracker/issues/1250

It appears to be a flake and retrying may work.

Can reproduce on Fedora 38.
