Indeed this helps greatly. The only remaining minor issue is that the
‘mount’ command still needs to be run as root. I have added the “user”
option and turn ‘mount.cifs’ into a setuid program.
(file-system
(device "//192.168.1.100/home")
(title 'device)
(options "uid=1000,gid=1000,credentials=/home/mthl/.smbfile,user")
(mount-point "/mnt/nas-home")
(type "cifs")
(mount? #f)
(create-mount-point? #t))
(setuid-programs (cons (file-append cifs-utils "/sbin/mount.cifs")
%setuid-programs))
However I am still unable to mount this as a regular user:
--8<---------------cut here---------------start------------->8---
$ mount /mnt/nas-home
This program is not installed setuid root - "user" CIFS mounts not supported.
--8<---------------cut here---------------end--------------->8---
What happens I think is that ‘mount’ calls the ‘mount.cifs’ from the
store and not to the one in the “/run/current-system/setuid-programs”
directory. I don't know how this could be fixed.
Thank you very much for this very helpful snippet.
