BUG REPORT: I am using following lines in /etc/fstab file to mount a samba shared (CIFS) folder on boot: //192.168.2.3/Seagates /home/edward/samba/raspberry cifs user,noauto,x-systemd.automount,x-systemd.device -timeout=10s,nofail,uid=1000,gid=1000,credentials=/home/edward/.smbcred entials,iocharset=utf8,sec=ntlm 0 0 Note, I am using noauto,x-systemd.automount,x-systemd.device -timeout=10s without which mounting does not happen during boot. Sometimes the computer that shares folder is turned off. When that computer is turned on later, I mount the folder manually by clicking the folder icon in nautilus. With above lines in /etc/fstab file, on manual mounting I get this error: screenshot on imgur( http://i.imgur.com/HVranvJ.png) which is mount error(22): Invalid arguments. from journalctl: Nov 14 00:33:30 flippingbits systemd[1]: home-edward-samba -raspberry.mount: Unit entered failed state. Nov 14 00:33:33 flippingbits kernel: CIFS: Unknown mount option "x -systemd.automount" "I mean the same option that helps mounting on boot gives error while mouting after boot" The manual mounting happens by non-root user if I remove systemd specific options: noauto,x-systemd.automount,x-systemd.device -timeout=10s or by removing user option which prevents me from mounting saying that only root users can mount.
