The ceph configure script is pretty good about checking for
minimum required versions of libs, etc.

I have a ceph testbed running on RHEL 6.2 using kernel.org kernels.
I use both stable series kernels, and Linus's master branch (usually
after -rc3 or so on each new kernel).  Occasionally a new driver
version for my hardware wants a new firmware blob, which is easy
to get from the kernel.org linux-firmware tree.
