Description of problem:
CIFS volumes can't be mounted as a normal user. The common suggestion is to add the setuid bit to mount.cifs, but this isn't possible to do on immutable distributions like Silverblue.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure a user-mountable / systemd automount CIFS volume
2. Try to mount it from Nautilus
I'm using the following fstab line for my volume:
//cupboard/data /mnt/cupboard cifs credentials=/etc/samba/cupboard.credentials,uid=1000,gid=1000,rw,noauto,x-systemd.automount,x-systemd.mount-timeout=30,_netdev,x-gvfs-show 0 0
The x-systemd.automount is recommended on multiple guides to delay mounting the volume until first accessed, instead of slowing down the system boot process.
