I've got up2date and yum2's header format support working on http://centos.karan.org/ repo's. Let me know if it works as it should.

If you intend to use this repository under up2date you need to add the following lines into /etc/sysconfig/rhn/sources ( on CentOS4, RHEL4, WHEL4, SciLinux4, Tao4 )


yum kb-centos-extras http://centos.karan.org/el4/extras/stable/$ARCH/RPMS
yum kb-centos-misc http://centos.karan.org/el4/misc/stable/$ARCH/RPMS


And as some people already found out - the x86_64 branch is now pretty much upto speed with the main sources tree ( i386 / x86_64 are both building in sync ).

Even if you dont intend to use up2date for the pkg management, its a good idea to setup these repos's in /etc/sysconfig/rhn/sources : that way the throbber icon ( red ! ) will let you know there are pkgs to be updated.
