Edit: I got it ("noauto" in /etc/fstab). Thanks everyone!  

I officially have a linux question!  

I have a mounted network folder on my linux mini pc. (Mounted using "mount -t cifs".)

Now I want to move my mini PC to a different place, where the network device isn't there *yet*. (But will be in the coming months.) What would I need to do to temporarily disable this mount (and later enable it again)?

I don't want the PC to fail on boot (or have a super huge boot time), so I think I have to do this. (Do I?)

Honestly, I don't know what I did with "mount -t cifs" and where the stuff is saved to, but it works - even after reboots. o.o
