When using workspace control 2.3 with a customization task and using a
partition for the disk, rather than a hard disk image (with multiple
partitions), mount-alter.sh crashes. I think this is because the hard disk
partitions have an offset parameter, and partitions do not, but the code
assumes there will always be this sixth parameter.

I have a hacky patch on github at:
http://github.com/oldpatricka/nimbus/commit/a4b265d1b5ece5b55a4b2858f94fb24547a63d6a

I'm sure there's a better way to fix this (maybe by moving the assignment into
the HDONE subcommand), but it should illustrate the problem.
