My current set up is:
I have my main machine (Darkseid) upstairs which has a drive with all my films on it, which I don't keep mounted.
Downstairs, next to the tv, I have a htpc (Archangel) which has xbmc installed on it, which points to a samba share on the main machine.
Everything works fine when the drive is mounted, but is there a script I can write to send a command to the upstairs machine from the downstairs machine to mount the drive to save the walk upstairs? #lazy
Both machines are Ubuntu 12.04
