[WBEL-users] Removing old kernel files

[david]

Folks

Since the original "respin-1", a revised and upgraded Kernel has appeared 
and works just fine.  All my systems have been rebooted and are using this 
new version.  To the best of my knowledge:

Old kernel: 2.4.21-15.EL
New Kernel: 2.4.21-15.0.4.EL

Ignoring the trailing ".EL", these names sort very nicely as alphanumeric 
strings.

However, I am somewhat cramped for space, and want to reclaim the space 
used by material I no longer use, like the old Kernel stuff.

Is there some syntax in "yum" or "rpm" that will do this for me, safely?

Thanks

David
