ext3fs

[raoul]

Hi all,

it seems on Current buildword from 4 January 2009
 that ext3fs is confusing mount:
ext2fs works fine;

so my question: is ext3fs supported?

here is my results:

mount -t ext2fs /dev/ad4s2 /mnt => ok
ls /mnt => Bad file descriptor
with a LOR:

GEOM_LABEL: Label ext2fs/debian removed.
