Hello,
I noticed strange output that I cann't understand.
term% cpu -h io
io% venti/checkarenas -v /dev/sdC0/arenas

term%
# note that arena.30 is NOT sealed. #
the difference between two output is only in arena.30
I don't understand where the difference comes from.
I believe that /dev/sdC0/arenas on io and /n/io.import/dev/sdC0/arenas mounted on term must be same.
I also believe that
venti/checkarenas -v file
consults only the given file.
