Package: eudev
Version: 3.2.9-5
Severity: grave
Justification: renders package unusable

Dear Maintainer,

I recently ran an update and booting failed (lvm disks could not be mounted). The underlying cause was that eudev was not starting.
This was probably (*) because a recent fix for container detection relied on the "head" command which is not available on my system early at boot (this
may be the underlying bug, I'm not sure).

I simply commented out the "exit" as can be seen below to make eudev start, this resolved all problems.

Cheers,

Danny

* I expected to have some way to see a history of the init file in a repository. But https://git.devuan.org/devuan-packages/eudev is outdated. I think this is a bad thing.
