wapbl: removing non-in-filesystem log

[Dieter Baron <dillo%danbala.tuwien.ac.at@localhost>]

hi,

while converting all my file systems to use wapbl, I ran into the
following problem:

# tunefs -l 0 /dev/wd0h                                      
tunefs: tuning /dev/wd0h
tunefs: Can't change size of non-in-filesystem log 

  How can I convince it to use an in-filesystem log?  (Note, I have
not (explicitly) created a log for this partition.)

Here is dumpfs's idea of the superblock:

# dumpfs -s /dev/rwd0h
