I did just that, I first listed to find all fossils:

ls /dev/sd*/foosil

which gave me /dev/sdC0 twise

Then:

% fossil/fossil -f /dev/sdC0/fossil -c 'srv -APW open' -c 'srv -p fscons'
% mount /srv/open /n/open

But there was no /n/open/active. In /n/open there was I filesystem very
similar to the one on the CD but with some files missing and different date
signatures.
When I tried to cp some file  there:

can't create "/n/open/PLAN9.INI" : mounted directory forbids creation

I had installed plan 9 using the option 1 of the CD and the 9pccd.gz in it
to run the instalation system. I am sure it installed, there were no errors
during the process and the progress bar took some time. When I boot I get
these 3 final lines:

using sdC0!9fat!plan9.ini
Boot devices: fd0 ether0 sdC0!9fat
boot from:

Then I tried sdC0!9fat!9pcdisk.gz but: error walking to 9pcdisk.gz

So, there is a plan 9 system installed, but I can not access it because the
plan9.ini is not well configured or does not mention the proper kernel file.
I can not depend on the floppy because it does not have vesa driver on it so
rio won't start. That's why I am trying to create or modify a plan9.ini file
on the instalation using the cd demo system.
Is it at all possible to do this? I mean, accesing the just installed system
using the CD demo and modifying or copying the plan9.ini file?
In case it is, why can't I write on the mounted fossil?
where should I put (or look for in order to modify) the plan9.ini on the
disk?
The booting system finds it on sdC0!9fat!plan9.ini
But I can't find it on the mounted fossil.
