do you know what could be causing this? (for some reason venti is not
posting anything in my http port)
is there some other way to get the
check you conf file, make sure you have http!*!80 explicitly in your
venti.conf.

Hello,
I am a little confused about setting up venti (on linux).
I followed the instructions found on the wiki, and venti is up. But
now I am lost; as far as I understood (from the man pages) I have to
run vac every time I want to backup something and then unvac it every
time I want to recover it,
You want to look at vbackup - that's what I'm using for my systems now.
Here's the script I use on my Linux system, at some point I may write
up something a bit more comprehensive about how to set this up, but
you can figure most of it out by looking at the man pages and code if
necessary.

Sounds vaguely like Freenet.

build an interesting dvcs with venti as a low-level
building block, and if so, how.
Well, the first suggestion may be how to partition venti, or is that a
silly starting point? Security definitely defeats, or at least
dilutes some of venti's strengths.

Yes, but even if one venti always leaves the store in a consistent
state, running two may still cause them to wite differemt things to
the same place on disk and this is likely to result in havoc.

I think /srv/dns serves an actual file system, so there are
potentially many references to it (not just one).

Given a fossil+venti holding a snap -a in, say, /n/dump/0101, is there a
way of obtaining the vac score for the root of /n/dump/0101 such that it
could be used to initialize a new fossil from the snap?
--lyndon
Vac prints the Venti score for a vac(1) archive containing
the tree rooted at dir, which must already be archived to
Venti (typically dir is a directory in the /archive tree).
so, from your example, you want (I think):
vac /archive/0101
vac creates backup

Perhaps related: fossilcons(8), talking about stat, says:

Has anything ever been done with this, or is this support still
