That was my original rationale, yes - but it no longer applies.  FreeBSD
now supports Ulrich's SHA-crypt (at least I see it in their source tree).

Right.  Perhaps we should enable c3_fmt for more systems.  And your
proposal is actually a good one in that context.

We could also enhance c3_fmt itself to detect salts for DragonFly's
broken SHA-2 stuff (now obsoleted due to our pushing).

I think it would work.  Do you know if it supports anything else as well?
