dfly-2.0.0-REL: panic: hammer: insufficient undo FIFO space!
I backed up my 5GB win2k ntfs partition to a disk image file on my Hammer FS
(6GB in size). When removing the image file, panic occurs.
To reproduce panic:
NOTE: assuming Hammer FS is mounted on /hammer dir and /root is symlinked to
# cd /root
# cat /dev/ad0s1 > c.img
# rm c.img

Ok, I'm on it. It's probably due to the tiny undo fifo one gets
when one has a tiny 6GB filesystem.

Yes, that's because the installer uses "-f" on the the newfs_hammer command.
By doing this, they have disabled the feature that protects us from a
too small undo FIFO.
