Help with fstab (mountpoint with space)

Hello.

I have recently bought an SSD-based Mac Mini and am very satisfied with it. However I had a few bones of contention with the relatively restricted storage space, so I opened it up and added an extra 1TB HDD, which I partitioned into three 'disks' to store (respectively) my Photograph libraries (500 GB), my Music libraries (300 GB) and MobileSync (200 GB).

Then I edited my /etc/fstab file to mount all the drives in filesystem hierarchy where I want them, and all worked fine.

Except MobileSync.

I am having problems because MobileSync's mountpoint lies within /Users/<me>/Library/Application Support/MobileSync/Backup, and that contains a space in "Application Support". I do not know how to successfully express that space in language fstab understands.

I have tried quotes

UUID=<partition-UUID> "/Users/<me>/Library/Application Support/MobileSync/Backup" hfs rw,noauto

and the old octal '\040' escape character

UUID=<partition-UUID> /Users/<me>/Library/Application\040Support/MobileSync/Backup hfs rw,noauto

Neither have worked so far.

I'm stuck. I need help.

Thanks.
