LXC suid/guid mapping

[kifeo]

Hi !

I deployed a LXC container and installed the ezarr suite : https://github.com/Luctia/ezarr
So the config part uid/gid are set :

drwxrwxr-x 8 13013 13000 4096 Nov 19 10:14 bazarr-config
drwxrwxr-x 3 13008 13000 4096 Nov 19 10:14 jackett-config
drwxrwxr-x 4 13003 13000 4096 Nov 19 14:15 lidarr-config
drwxrwxr-x 4 13009 13000 4096 Nov 19 10:14 overseerr-config
drwxrwxr-x 3 13010 13000 4096 Nov 19 10:13 plex-config
drwxrwxr-x 6 13006 13000 4096 Nov 19 16:20 prowlarr-config
drwxrwxr-x 4 13007 13000 4096 Nov 19 10:14 qbittorrent-config
drwxrwxr-x 5 13002 13000 4096 Nov 19 14:15 radarr-config
drwxrwxr-x 5 13001 13000 4096 Nov 19 14:15 sonarr-config

And I wanted to use the data part as NFS, so I used the mountpoint method of host NFS mounted source mountpoint.
This gave the nobody:nogroup on the NFS due to the uid/gid mapping.

So I used https://pve.proxmox.com/wiki/Unprivileged_LXC_containers
(I use only 3 uid mapping)
lxc.idmap: u 0 100000 13001
lxc.idmap: g 0 100000 13000
lxc.idmap: u 13001 13001 3
lxc.idmap: g 13000 13000 1
lxc.idmap: u 13004 113004 52531
lxc.idmap: g 13001 113001 52534

So this works ok now for the uid/gid of the NFS mountpoints, BUT the config part where the uid/gid (that should be the same as the NFS) are now unmapped and show nobody:nogroup.

I wanted to know if there is a way to set the previously mapped uid/gid to the new mapped.
OR if I have to do the mounting first and reinstall.

Thanks !
