Ubuntu gutsy gibbon update fstab problems
Extra partitions can no longer be accessed via standard /dev/sdxn (x=a,b,c etc, n=0,1,3 etc) references, instead /dev/mapper/sdb5 style references should be used.
If one tries to mount a drive via /dev/sdxn a rather confusing message is displayed.
mount: /dev/sdb5 already mounted or /mountpoint busy
This implies the volume is already mounted, which it is not.
The symlinks in /dev/disk/by-uuid (used if you use UUID references in fstab) also point to /dev/sdxn references.
Interestingly additional drives added after startup such as external USB drives are accessible via /dev/sdxn references and not /dev/mapper/sdxn.
