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):

cifs-utils-6.15-1.fc36.x86_64

How reproducible:

Always.

Steps to Reproduce:
1. Configure a user-mountable / systemd automount CIFS volume
2. Try to mount it from Nautilus

Additional info:

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.
