Great, so more testing to do /o\

Nanar will be able to do it, even if hosting a small database like this
may not be very appealing to him. There is just 5g, when compared to
sophie, I let him give the numbers.
But I would prefer to have it hosted on mysql if we later migrate to
another vm. The lag Marseille <-> Toulouse will not be good if it can be
avoided. We could also setup a different postgresql server on the forum
vm in this case.
In any case, postgresql to mysql conversion doesn't look doable.

I would prefer to have it hosted on our servers, for various and obvious
reasons ( like : "handling the auth and permission ourself" "proper
bugtracker integration", etc ).
But we are not ready, see my answer about gitorious. So here is a
proposal in 4 steps :
- we do a git checkout every 5 minutes ( just need the url, and
Later ( like short term ):
- sysadmins do work to have a git repository, who will be the exact
state of production, and be the reference. That where changes are
pushed, and where the server take his checkout. So this way, the project
handle who can push to it using ldap (unification of auth, delegatation
Later again ( like mid term ) :
- you express your needs in term of hosting ( like what type of hook,
requirement in term of web interface, "need to do review" "need to show
dancing hamster" , etc ) when we do a call for that ( you can do before,
but this will potentially be lost ).
Once we have installed this :
- you switch to our infrastructure.

Since we do have puppet and can clone machine, I would then prefer to
have a separate vm for test than for production, unless there is problem
with the intended usage (like you really need to have the exact same
hardware, for load testing purpose ).

Could we do it with a master/slave replication without much trouble ?
( and possibly, one that would automatically recreate the db once it is
Or we can do snapshot using lvm, but I think this can be quite fragile.

As said, I would strongly favor a automated deployment using git, at
least on production server.

As I said, if people want us to host git, there is a few questions to
answer first ( I guess that 2 weeks to gather requirement should
suffice, given proper flamewar handling )
