Internet Virus: SunOS patches

[scritzifchisted ulmo qzutvchsxik]

I'm a totally ignorant Unix user, but there are a few common sense things
I might add to this having to do with permissions of old copies lying around,
in case you didn't remember:

I know, this has got to be really petty.  But, now that everyone knows
how debug works, it's probably best to make sure someone doesn't use those
good old root powers for something they've been wanting to do for awhile ...
(on the most part, I guess people are pretty good about this sort of thing).
