A permissions matter about metadata on Linux

[Vast]

I'm using Jellyfin v.10.10.6 on TUXEDO OS 4  (Ubuntu based).
I noticed that the metadata files including the trickplay directories and their content have jellyfin as owner and group respectively. The media files themselves (mostly mkv) have my username as owner and group.

One problem that arises is that I cannot delete directly the metadata, because I'm not trying to do it as jellyfin. The only practical way that I know to have permission to delete metadata without being jellyfin as owner is to use the following to set default ACLs on the parent directory where the metadata are kept:

Code:

sudo setfacl -d -m u:vast:rwx /media/vast/MediaFilesDirectory
sudo setfacl -d -m g:jellyfin:rwx /media/vast/MediaFilesDirectory

Code:

getfacl /media/vast/MediaFilesDirectory

shows:

# file: media/vast/MediaFilesDirectory
# owner: vast
# group: vast
# flags: -st
user::rwx
user:vast:rwx
group::rwx
group:jellyfin:rwx
mask::rwx
other::r-x
default:user::rwx
default:user:vast:rwx
default:group::rwx
default:group:jellyfin:rwx
default:mask::rwx
default:other::r-x

Although the above works, I'm wondering if I could have installed jellyfin in a different way in order to avoid the issue about deleting metadata as the user that normally uses the PC.
