Obviously people have to have the option of using old style
formats. However, I'll point out that crypt(3) is creaking badly. The
cost of simply brute forcing an arbitrary password regardless of how
obscure it happens to be is getting dangerously close to
practicality. MD5, or even better, SHA, is a far safer bet for the
long term.
