I have network drives set to automount on first use. Here is a typical /etc/fstab line: //<server>/Media /mnt/<server>/Media cifs noauto,x-systemd.automount,user,guest,noperm,dir_mode=0x777,file_mode=0x777,vers=1.0,rw Note that without the 'noauto' it *will* automount on boot, which is not what you normally want for network or removable drives, given that the boot will hang if the drive is not found. I believe 'nofail' instead would also prevent a boot hang, but I also don't want a dozen possibly delayed mount processes holding up boot, I'm prepared to wait until I need them. Note that most of the parameters are relevant to cifs/samba mounts. With no /etc/fstab entry, a removable drive when plugged in will by default automount on first use. I don't recall that any manual configuration was necessary for that to happen. -- Joe
