You can use nested labels. You can a create a bsdlabel inside a bsdlabel.
I don't know the limit of nesting. I doubt you'll ever need more than 7**2
partions, or 7**3 partitions, or ...

Then you can use glabel to assign names to the partitions, so you won't
have to remember the exact partioning scheme. It will look like this:
/dev/label/jail_01, /dev/label/music, /dev/label/src
