All of those worked fine as far as I can tell:
term% ls -l /dev/sd00
--rw-r----- S 0 glenda glenda   104857600 Jul  1 11:42 /dev/sd00/9fat
--rw-r----- S 0 glenda glenda           0 Jul  1 11:42 /dev/sd00/ctl
--rw-r----- S 0 glenda glenda 69379563520 Jul  1 11:42 /dev/sd00/fossil

but that one failed:
term% fossil/fossil -f /dev/sd00/fossil -c 'srv -A fossil' -c 'srv -p
fscons'
fossil/fossil: bad config magic in /dev/sd00/fossil

then I wanted to check for something suspicious in my config:
term% fossil/conf /dev/sd00/fossil
config has bad header

Is that bad?

Gonna reboot to the native plan9 in the meanwhile to check if
everything's ok...
