yes, and 0.6.x is the only one we 'officially' support for CentOS3/4/5 -
none of the other newer releases work for and with CentOS - so keep that
in mind.

Were not fedora, and were not upstream for mock either. So keep that in
mind.

That was not my point of asking. I just wanted his patch to go into
upstream for future releases too.

you can perhaps just script around mock to do the snapshots after an
init. Just remember to keep plenty of COW space for the snapshot so it
survives a large build run

At the moment, not in CentOS-6. The problem I have now is that quite a
lot of the buildsystem state and policy is static to the machines its
running on and plague is just a wrapper around the real scripts. It
would be trivial to use something like rabitmq and actually completely
lose the plague setup around the buildsystem. something that is very
much on the cards. Its just a case of working out who is going to do the
stuff and how and what the scope of something like this might be.

However, the base common denominator is still mock and I dont see that
changing in the near future. Also, while we still support and work with
CentOS-3, its quite nice to see us support it. Is there anything in
mock-0.9 that results in a build output that is different from the one
that mock-0.6.x is able to produce ?

Mock 0.9.x works pretty well on Centos and with Centos...

I just pull the mock from epel and use it on a stock COS5 box. There
are some dependencies but they can all be satisfied by epel as well.

[slords@b64-5 mock]$ rpm -q mock python yum
mock-0.9.14-2.el5
python-2.4.3-27.el5
yum-3.2.22-20.el5.centos

Why would you need to run it on cos3? You just need to create a config
file that populates a cos3 build env.

we have buildservers running across c3/c4/c5 - and I know atleast a
couple of people who are in the same situation.
