To the best of my knowledge, all the macros have been posted on this list over
time. I've rebuilt probably half the ATrpms repo for RHEL3 and Tao Linux
without a problem using them (as well as a number of packages for YDL).

Completely tangential and, IMO, a bit off the deep end. I won't argue with you
beyond that, but there's no way in hell I'm putting anything BUT a common,
rpm-installed kernel on all my production machines at work...

It seems you've missed a number, everything I've got has been on the list. So
I'll just repost them all.

The large majority of the SRPMS rebuild just fine if you have the %atrelease
macro alone...

Please see the end of this message. I have yet to find a SRPM that didn't
build with the macro set I have.

The build dependencies are all in the spec files, once you have enough macros,
you're fine.

I think that is a fine idea. I think it would help to reduce noise on the
list, and bring up the signal level a bit, as folks that haven't been able to
find all the macros wouldn't have any excuse to not be able to
rebuild/fix/upgrade ATrpms packages. Axel?

More or less like this:

# rpm -ivh package.src.rpm
# vi /usr/src/redhat/SPECS/package.spec
# rpmbuild -bb /usr/src/redhat/SPECS/package.spec

Seriously, just a few tweaks to spec files, and the vast majority of packages
rebuild on systems without any of the custom macros.

True. And ATrpms would indeed like more people to help out. I'd like to do
more myself. I'll agree that many of the macros are a bit of a nuisance (esp.
when you don't have them), but many are also very necessary to make managing
such a large repository that spans so many distributions doable.
