Anyone have rebuilt glibc (x86/32) rpms for RHEL 4/Centos 4.1 with the gcc's -mno-tls-direct-seg-refs flag available around ? (to avoid performance drop on top of a NPTL based Dom0). Unfortunatelly we have around a closed source app that breaks if i disable NPTL...

I would be willing to test if you can get a hold of them. Too busy to rebuild myself (and haven't used rpms in a while).

As a side note, I used the great images at http://jailtime.org to jumpstart a centos 4.1 and zimbra install, but had all kinds of problems until I re-enabled /lib/tls. I would love to see if this would help and get rid of all the warning messages from xen.
