I still operate under the assumption that glibc and kernel updates require a
reboot to be prudent on a Linux OS.
With CentOS Xen 5.6 (standard installation, SELinux enabled) is there an FAQ or
general user consensus as to when to do a reboot after what updates?
Same here. Thank you very much Alexey for sharing this.

Hmnn. I had done that prior.
I had a CentOS 5.5 Xen standard virtualization install lockup on
reboot after an battery backup (apcusbd) orderly shutdown induced by a
power outage. It may have been sitting with two kernel updates without a
reboot.

It's probably just that fsck can't automatically fix some dirtiness and not a

Thanks for sharing Grant. Your point about hardware raid is well taken.
However, the discussion is about Fake-Raid vs. Software RAID1 and
controller/chipset dependence and portability. The portability of a

learned, much higher
