This is FC5T1 (with some updates from devel). If I try to run yum update, it says: Removing: kernel x86_64 2.6.14-1.1696_FC5 installed 84 M kernel x86_64 2.6.15-1.1826.2.9_FC5 installed 82 M Seems to be acting as if it doesn't recognize these as kernel packages that should be installonly. The yum config is stock FC5T1.
