Problem Description

Description

I am using the Beszel binary agent on Linux with two additional filesystems configured through EXTRA_FILESYSTEMS:

• /media/video__Video
• /media/backup__Backup

Only Video appears in Beszel. Backup does not appear in the UI and is also missing from the agent debug output, even though the mount exists and is accessible.

Both mount points are configured in /etc/fstab with noauto,x-systemd.automount,x-systemd.idle-timeout=10min.

Only /media/video is detected.

/etc/fstab

UUID=6e53019c-b9a6-4958-8225-cf6bc8fb6f5d /media/backup ext4 noauto,x-systemd.automount,x-systemd.idle-timeout=10min 0 2
UUID=E7DE-D1A1 /media/video exfat noauto,uid=1000,gid=1000,x-systemd.automount,x-systemd.idle-timeout=10min 0 2

Mount state

mount shows both automount layers and both real mounted filesystems:

systemd-1 on /media/backup type autofs (...)
systemd-1 on /media/video type autofs (...)
/dev/sdc1 on /media/video type exfat (...,x-systemd.automount,...)
/dev/sdb1 on /media/backup type ext4 (...,x-systemd.automount,...)

Additional checks

The backup filesystem is accessible:

ls /media/backup
lost+found/  restic/  timemachine/

Restarting the agent after explicitly accessing /media/backup still does not make it appear.

Expected Behavior

Both /media/video and /media/backup should be detected and exposed as extra filesystems.

Steps to Reproduce

1. Setup 2 automount point in /etc/fstab
2. Add them to EXTRA_FILESYSTEM
3. Start beszel agent
4. Only the first one is detected.
