I recently have had an odd thing happened, I rebuilt my system, and all
the passwords were suddenly invalidated.  The clue I get is from running
vipw, where the old passwords (in encrypted format) don't seem to follow
any paatern, but the new ones are all prefaced by "$1$".  I need to
upgrade a machine that has a lot of existing passwords, and I really
can't afford to lose them all, so I need to see what happened and avoid
it.

Can anyone explain this to me?  I suspect something with regards to
maybe md5 formatting or something, but I don't know the right man page
to read to figure this one out.
