Describe the bug

I updated nixos-unstable yesterday and now I get error from the front end, that all media files are unavailable.

Steps To Reproduce

Steps to reproduce the behavior:

1. Setup plex
2. Setup some media library
3. journalctl will tell that plex can't access files:

May 23 05:29:26 servi PlexMediaServer[53327]: Couldn't check for the existence of file "/home/plex/Movies/.grab": boost::filesystem::status: Permission denied [system:13]: "/home/plex/Movies/.grab"

Expected behavior

Before updateing nixos-unstable it worked fine. Now it doesn't. Reverting back to previous generation (from beginning of may) also makes it work fine.

Additional context

By default I set ownership to plex:users of the /home/plex/ folder and files. Folders have 0755 permissions, files have 0644.

I tried also adjusting the group to plex with same result.

I also tried ACLs

getfacl /home/plex/Movies
getfacl: Removing leading '/' from absolute path names
# file: home/plex/Movies
# owner: plex
# group: users
user::rwx
user:plex:rwx
group::rwx
group:plex:rwx
mask::rwx
other::rwx
default:user::rwx
default:user:plex:rwx
default:group::rwx
default:group:plex:rwx
default:mask::rwx
default:other::rwx

None of this helped.

I reverted now back to an older generation and it works fine again.
