Yes, I did it. Just let /var run full and try to log a lot of stuff and
you will write the same sector many times in a short period. Lead to an
unusable /var partition on a consumer SanDisk CF Card. The card was
pretty old, but I guess that there are a lot of low price CF cards out
there that have no real wear level algorithm implemented.

Putting /var on mfs is not such a bad idea if you got RAM to spare.
Using rsync to write the changed files back on the CF card in fixed
intervals and on shutdown should be ok.

Nice theory, would explain some hardware faults I witnessed in the past
:)
