Adguard-Home: Too many Open Files

[alxbl]

AdGuard-Home deployment won't start anymore because of inotify.

This works:

# On the host
sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl fs.inotify.max_user_instances=512

But it needs to be made permanent as part of node provisioning.

It's actually because adguard shares the same uid as jelly fin (https://github.com/jellyfin/jellyfin/issues/7684)

Possible fixes:

• Use different uid for jellyfin (isolate it)
• Configure Jellyfin to not use so many inotify watchers
