I agree and I thoroughly endorse giving students root access to their
"personal use" systems.  Book learning is valuable without a doubt, but
there is no more valuable lesson for a would-be sysadmin than the one
that follows from an "Oh S**T!" moment.  In fact I would go so far as to
say that the sysadmin training is not complete until the person has sat in
front of a system that is no longer functioning perfectly (or at all) due
to some ill-advised thing they have done.

One of the things I have always appreciated about the *NIX OSes is the
ability to completely trash an installation but then to recover assuming
only that you have the installation media and good backups. (Which
backups have been proved to be restorable.  How many people do backups
but don't bother to check that they are good?)

Another valuable resource when trying a recovery from a bollix is a list
like this, of a sysadmin who has made about every possible kind of screwup
and had to recover.  [In 20+ years I may be qualified.  Looking back it
would seem possible ;^) ]
