fossil is not a proper cache. fossil uses venti for archival snapshots
(this would be called a dump in ken's fileserver). fossil is useful
without venti. in fact, i think fossil without venti is better for a
combined auth/cpu/fileserver as fossil is much kinder if you turn
the machine off or hang it.
the downside is if you do have a venti,

this means you can connect to different file trees. so i can connect
to kibbiee like this
; srv il!kibbiee kibbiee
then mount the other filesystem, dump or main respectively
; mount /srv/kibbiee /n/other other
; mount /srv/kibbiee /n/dump dump
; mount /srv/kibbiee /n/kibbiee
the 3d argument to mount is the "attach point". the server is free
to choose a default, which for ken's fs is "main" and for fossil is "active".
fossilcons(8) explains how to make different fossil filesystems. typically
all you need is one.

yes. you don't get archival snapshots without venti. you could
use vac to roll your own.

you'd have to do this manually. you get one archive per day.
