I noticed on htop that kde wallet was using cpu so I was looking at my services to try to shut it down. I noticed shadow had failed bc of missing entries in /etc/gshadow. I added them with grpck and the service starts and completes fine now.
However, I’m not sure how the entries came to be missing in the first place . . how might I track this down?
Not sure if it’s relevant but grub-btrfsd also failed on account of .. apparently a number of things . . First was missing inotifywait and now no directory found at /.snapshots. I installed inotify-tools but I’m holding off from satisfying all of its complaints for now until I understand how they popped up in the first place. I just started looking into it so no answers needed on this count rn. (not saying I wouldn’t accept tips 
)
edit: the missing groups were: uucp, nopasswdlogin, rfkill, and sys
edit2: EnOS installer did my filesystem and partitioning
