since we control the structure, why not the (slightly uglier)

/root__active
/root__rollback
/root__20090807
/home__active
/home__...

just remove the slashes or replace them with some other character like 
dash or underscore.  `ls` will still sort things alphabetically so there 
will still be some semblance of order for the humans, and it would 
behave nearly the same to the machine.  And it will be easier for 
debugging purposes if all these subvolumes are accessible by name.  (Do 
you think you can ask upstream whether they want to change or keep the 
restriction on slashes(i.e. volumes in subdirectories), in light of our 
'.' organizational ideas?)
