Asking for root passwd when booting single user

We've been using the following technique for several years without any
problems, but I don't guarantee it: put the following in the file
"/.profile":
trap exit 2 3 15
PATH=/etc:/usr/bin:/bin:/usr/ucb
login root
This causes the system to prompt for the root password when booting
single-user, and, if it doesn't get it, it immediately boots multi-user
instead. **This assumes that root's shell is "/bin/csh"!!**. If it's
/bin/sh, you won't like this "solution".
The login will time out in 60 seconds, so don't be slow if you mean to
boot single user.
Of course, SunOS 4.0 can be configured to require the root password
anyway, so this technique is already pretty dated.
