uninstalling custom kernel and query on stale files from previous kernels

[Matt H.]

Hi
I built a custom kernel from the 2166 sources -- 2.4.22-1.2166.nptlcustom.
However, it's time to delete that as newer updates are available. So,
would deleting all entries in /boot/, /lib/modules/, and the grub.conf
entry relating to 2166.nptlcustom be all that's necessary?
 
Related to this is the question: How can I custom build a kernel, based
off the latest available, say 2174, as an rpm so that it can be easily
uninstalled or updated via up2date? Rather than going through the make
xconfig ; make dep ; .. etc. process.

The other query I have is looking in /lib/modules and /usr/src, there's
still directories for 2.4.22-1.2149, even though I've updated to later
releases. Is it fine just to delete these 2149 entries?

Thanks guys (and gals!)
