Since ip-up is executed as root, that depends on exactly how little
security you want.

If you want to do this, you should probably give up root priviliges
before running ~/ip-up.  But you can't trust $6 anyway, so you'll need
to get the userid from somewhere else.  I use the GID to identify
users in my Perl ip-up script.
