[Yum] Kernel Updates

[Greg Kurtzer]

Forgive me if I just missed this (although I don't see it in man 5 yum.conf), 
but is there a config parameter that can be set which will disable changing
the default kernel to what was just installed?

For systems with 3rd party kernel modules for hardware devices (ie. SCSI),
this can be a fatal issue when 'chkconfig yum on'.

Thanks,
Greg
