For the record, my problems occured with 5.4-PRERELEASE #1
which, for reasons beyond my control, I had not yet been unable
to upgrade.

What bsize/fsize ratio are you using? Mine was 4/1 instead of
the more usual 8/1.

BTW, anybody know what the best method be for double-checking
df's figures would be? du?
