Why? Just use it as a backup version. No need to rename anything at all. I never rename a kernel, Sysmap, module dir or anything when trying out a new kernel. I use EXTRAVERSION instead - for its intended purpose - which was to eliminate these sort of problems.

How could it possibly add any uncertainity about anything? My kernel is 2.4.2-2 right now. If I build a new one, it will be 2.4.4-1asdf probably (asdf is my machine). If I then want to try a new kernel but am not sure if I want the old one still, the new kernel will be 2.4.4-2asdf. None of the kernels have files that conflict, and the names of them never change. I add a new stanza to lilo for the new kernel, run lilo, and can easily boot any of the kernels.

Better yet, rewrite those broken scripts to work with todays kernel features. My install-kernel script works just fine for adding a new kernel to the system.
By using new tools you avoid old problems.

Cost isn't as important as is functionality and quality. Any suggestions appreciated. ------------------------------------------------------------------------
