The first thing that pops to mind is write your own "shell" and do something
like this:
#!/bin/sh
echo "Your account is locked until you clean your room"
logout
stash that in /bin/custom_shell
make it executable (and w/ -rwxr-xr-x permissions)
Then just
sudo chsh /bin/custom_shell username
I'm sure there are probably buffer overflow/etc type issues if this was a
real production type issue, but based on the message, I'm guessing that
it'll do.. I haven't tested the above, so perhaps the chsh command is a
little different (I'd just edit /etc/passwd, but some folks are squeamish
about that kind of stuff..)
