ext2 or ext3 usage

[Matthias Rampke]

Hi,

this may have changed somewhat recently, but last time I attempted to
use ext2/3 under *BSD (which AFAIK mostly share the driver) the
situation was:

* ext3 won't work
* ext2 created with the default mke2fs settings won't work (unsupported options)
* very basic, oldskool ext2 might work, but I haven't found the right
settings yet

I didn't pursue it further at the time.

Best,
Matthias
