on intel-based hardware this is always going to be the case..you can boot
off floppy. if you disable floppy booting, you can go into bios and
re-enable it. If you password the bios, you can short it so it loses it's

appropriate line in the script and fix it (I recently did this for our
webserver, and it worked just fine :) )

what happens if you try to create their directory by hand?
as possible work around is to create a shell script that makes the
directory and then calls useradd
also, have you tried using the adduser shell script that came with redhat

when it comes to security, it's what you should *not* install and what you

the problem with using just one partition, is that if your system goes
down ungracefully (i.e. power fails, someone hits the switch, etc etc)
it's going to take one *heck* of a long time for a larger drive to fsck.
