There are a number of reasons, not all of which will apply to any
1) [as Wojciech Puchar said] tradition. Not an especially good reason
on its own.
2) keeping problems on one partition from raising trouble on another
partition. e.g., filesystem corruption in a home directory keeping
the root from being able to boot, or filling up a mail directory
keeping people from logging in.
3) fsck: Background fsck can't be done on the root filesystem, so if
you have a large root, that amounts to a substantial delay booting
after a crash.
4) backups: dump(8) works on a filesystem basis, so organizing the
data for backup (with dump) means organizing according to
filesystem. The same applies to snapshots.
