I'm trying to mount
/var/folder to the same external volume UUID=xyz. This external volume already has subdirectories
var_folder and has been formatted and available to mount. I want to change fstab and achieve something like the following, before doing "mount -a":
UUID=xyz:/etc_folder /etc/folder ext4 defaults,nofail 0 2 UUID=xyz:/var_folder /var/folder ext4 defaults,nofail 0 2
But this doesn't work... what exactly should I put in fstab?
