Re: CentOS/RHEL support
if im reading this correctly you are asking if a kernel-debuginfo
package from RHEL would work with a kernel from Centos with same
NEVRA? If so, then unfortunately the answer is no.
With kernel's built in RHEL, Centos there is no associated build
information build into the elf headeres or anywhere for that matter,
so we rely on the build timestamps from the kernel. With that we then
match the build timestamp from the core with timestamp gathered from
the vmlinux and voila!
The hidden layers of cas is quite simple its just putting it all
together nicely :) So for this case you would need a centos debuginfo
package for the centos kernel and so on.
Hope this helps!

gets interesting is that I tried running CAS on a core from it:
[root@dhcp-149 ~]# cas -i 1 -f 2008-1215-1219.59-rhds-1.70.core

3.4.6 20060404 (Red Hat 3.4.6-10)) #1 SMP Tue Aug 5 11:25:12 EDT 2008)
with debugKernel
So I tried finding the debuginfo from CentOS (can''t find it, I'll
take that up with the CentOS guys). But even if I did, would it work
since I have a RHEL debuginfo of the exact same NEVRA? Food for
thought....
