Seems to work okay in some quick testing on a rawhide i386 box. anaconda built fine. On the other hand, the mach package is missing a buildrequires on libselinux-devel ;-)
If I'm not snowed in tomorrow, I'll try to do an install on an x86_64 box and see how things go there.
I installed on an x86_64 box. FC3 but made an installroot of rawhide. The installroot works fine - but rpm commands flake out when you run them from the outside of the chroot. Oddly yum --installroot commands work just fine from the outside.
anyway - if we run on the same rpm version we're building for it shouldn't be a problem. I'll install the other opteron tomorrow and see if I can get a mach x86 chroot running on x86_64 w/setarch reasonably sanely.
if we can get there then maybe a mass rebuild can be:
for pkg in * do if [ -d $pkg/devel ]; then make srpm fi done
find ./ -name *.src.rpm | xargs mach rebuild
with a lot of disk space available :)
