Put them into common and comment all the lines so no files are included in the
image.

I think you should replace nc by the version that is in RHEL/Fedora then.

This is probably quite difficult. I would prefer a lfs/nmap and a seperate
lfs/netcat. That will generate a single rootfile for each of them and you can
decide what to do with each of them.

Hope this answers the questions. If not, please mail back.
