Hmm, for some reason I decided on ~500MB /boot on the CentOS6 systems I
built.

I've seen, but not used the yum.conf option for kernel retention.
Not many kernels would fit, so in my case cloning was the best option. :-/

Yeah, having to deal with it being out of space stinks.
I've gone through it on a system where a former sysadmin set up a 100MB
/boot partition for that CentOS6 server. Eventually I managed the time to
clone the system so that the /boot partition was 500MB.
( What a pain in the butt until I fixed it! )
