This has nothing to do with the shell. This is an admin question,
crossposting to comp.unix.admin and setting followups there.

1. You have a unitary file system, which is both a common and
reasonable setup for a home system. You don't have a separate
filesystem for /home, /tmp, /var, /usr or just about anything
else. It's all in /, except for a small auxiliary partition
/boot which holds your kernel and a few files associated with
your bootloader.

2. You can't set separate quotas for /home and /usr because
they aren't separate filesystems on your system. You can
only set a quota for /, which will be a quota for your
whole system.

3. If you move files from a filesystem with quotas to one
without, the file will not count against the quota on the
old filesystem (as it no longer on the old filesystem) nor
will it count against a quota on the new filesystem (as
the new filesystem has no quota for it to count against).
Quotas are simply applied to your usage on your filesystems;
they don't follow files around. This, of course, is not much
of a concern on your system, since you only have one filesystem,
so the user is not going to moving files from one filesystem
to another.

BTW, I notice your filesystem is only 4% full. With 190
gigs of disk, you probably won't be running out anytime soon...
