I had a situation pop up recently where I needed to mount an SMB (CIFS) share from a WIndows server on an Ubuntu based machine via the fstab, but hit a small snag - spaces in the share name. Why in the name of all that is good Windows admins insist on doing this is beyond me, but I did find a good blog post on how to deal with it without involving ammunition.

Simple character substitution... nice!
