[NTLUG:Discuss] Disk cleanup

[Leroy Tennison]

My disk is filling up (surprise, surprise) and I'm looking to clean up 
two known issues: yum "leftovers" and too many versions of the kernel (I 
only have nine of them).  However, when I look at 'man yum' the 'clean' 
option seems to be an all-or-nothing proposition.  I was hoping for 
something like "clean all but the last update".  I also know that I can 
just delete old kernel variants and edit grub.conf/menu.lst but that 
doesn't deal with all the files under /lib/modules.

Is there an easy, safe way to accomplish these tasks?
