Hello,
I'm gradually getting more involved with EPEL, have already built a couple of
packages yesterday and will ask branches of some others soon.
However, my interest is almost exclusively limited to EL-5 at this time.
While I'm not going to make any gratuitous changes to packages that would
cause them to not work on EL-4 and will test at least to some extent with it,
I probably won't be requesting any EL-4 branches nor really promise to
actively maintain packages for it.
So, if you want some packages for which I'm listed as the sole EPEL maintainer
to appear for EL-4 and volunteer to co-maintain them (for EL-4 only or for
later releases too), that's welcome, let me know.
One such example is cvsps - it was listed in EPEL 4 broken deps report,
required by git-cvs. For EL-5 it has been branched and built and will
probably appear in a push soon, but I have no plans to maintain it for EL-4.
