well to clarify things. ext2 is not reserving space for the superuser
at all, it simply reserves a certain number of blocks (by default 5%
of the filesystem, set at mkfs time) for a certain uid and gid, the
default is 0 0, which under most traditional systems happens to be the
superuser.
under ext2 you can just as easily give this reserved space away to any
user, or a group of users. man tune2fs.

semi inconvenient, but if your adduser allows hooks (like debian's)
its not that difficult to automate.
