Y'all seem to be misinterpreting my original statements (or, more
likely, I was less coherent than I thought) -- the alias is merely a
single, semi-beneficial, slightly-annoying but attention-getting tool
in a sysadmin's potential toolbag. It's not going to absolutely
prevent catastrophe (a fact of which I have first-hand,
did-I-just-delete-2TB-of-production-data? knowledge), but it IS going
to make for a nice tripwire that will catch at least a few braindead
moments at the end of 80 hour weeks.
