Just incidently, it seems that support for ext2fs in -current is broken
right now, having had occasion to use it over the last few days. I
haven't had time yet to diagnose it in detail, but mention it now in
case someone has some ideas already and save some time. (Bruce? Are
you listening?) Sympoms are "block already freed" errors when
writing to the ext2fs filesystem, and eventually (sometimes very
quickly) a complete system freeze - no panic messages at all, no
ddb in spite of it being in the running kernel. Mounting it read-only
seems safe and stable enough, so I'm doing that for now.

FS code, particularly on -current, is way out of my league. :-)

David
