Not to fossil, but we're using this to move our worm into vac, which
can be serviced by venti. 9fs automates it for us.

#!/bin/rc
# mkvac: creates one vac archive. argument is day number.
#

srv -q il!sargazos.escet.urjc.es
mount /srv/il!sargazos.escet.urjc.es /n/dump dump
date
vname=`{echo $1 | sed 's|/|_|g'}
lname=`{cat mkvac.last}
echo vac -s -b16k -f dump/2002/$vname.vac -d dump/2002/$lname -q /n/dump/$1
time vac -s -b16k -f dump/2002/$vname.vac -d dump/2002/$lname -q /n/dump/$1
echo echo $vname.vac '>' mkvac.last
 echo $vname.vac > mkvac.last
unmount /n/dump
rm /srv/il!sargazos.escet.urjc.es
date


This other one calls the previous one to automate it:
#!/bin/rc
days=(0508 0507 0506 .....other preferred days here)
for (d in $days) {
	cp /dev/text /n/once/nemo/mkvacs.out
	echo -n $d starts ' '
	mkvac 2002/$d
	echo
}
exit


We are doing 1.5 months per day or so.

Congratulations!

I feel a bit adventurous -- but also in the need of
a little (or more?) hand-holding.

I have browsed through the setting up docs on wiki,
and a couple of the refered man pages, but
could not easily see how to build a fossil from
(to replace) an existing fake-worm file server,
taking into account the dump partition.

I recall reading before that at bell labs worm
disks of the fs were copied ``by hand'' one by one,
by taking them out of the fs.
Is there a way to transfer dump to fossil from
a running fake-worm fs (so, just using normal 9p
access, without going to the ``raw disks'')?

On a related note: my fake-worm fs uses relatively small
blocks (4Kb). Can I freely choose a block size for the
venti underlying the fossil, or should there be
a strict relation between the fake-worm  block size
and the fossil/venti block size (e.g. due to transfer
of dump blocks)?

Thanks for any insight (pointers welcome),
Axel.
