Ok,
Installing the X11 iso on a fossil based file server.
# start the iso9660 filesystem server
9660srv
disable the 9fs command by binding echo over it
bind /386/bin/echo /rc/bin/9fs
# mount a psudo /n/kfs pointing to the root of your fossil filesystem
mount /srv/boot /n/kfs
# the below is from the standard X11 install instructions.
# mount the iso
mount /srv/9660 /n/dist /n/juke/X11.iso
# initialise the replica logs
/n/dist/X11.setup
# do the pull
replica/pull /n/dist/X11
# have coffee, even installing takes 10 mins...
