[CentOS-devel] CentOS 7 (1503) i686 Beta Architecture

[Jim Perrin]

I'm not opposed to that, so long as *something* (disttag?) changes, so
that we don't end up with the exact same package name built with a
different gcc option. The potential for silent problems due to identical
looking package naming with different build options is much higher.

If you can come up with another few people to help you out (so that it's
not relying entirely on one person), then it's something we can
seriously discuss without the need for hypotheticals.
