I was under the impression that the LINT kernel was the one that had every
option under the sun (not SUN).
Years ago, I wrote a kernel buiding script that, when given no arguments,
would use the 'GENERIC' kernel. No Problem. When you specified a name
that didn't have a Config file, though, I neede a file that had more than
the GENERIC config. I started copying LINT to the new file and using that.
Also, my personal opinion is that the GENERIC kernel should have a
reasonable amount of bloat built in. This isn't the floppy install, after
all. It can afford to be relatively large. Putting NFS, Quotas, verbose
messaging, etc. in the GENERIC kernel are all OK for me.
One thing that I haven't seen go by is the possibility of putting three or
four kernels into the kern.tgz file (a GENERIC IDE minimal kernel, a 'four
meg of memory' kernel, a FIREWALL kernel, and a ROUTER kernel, for example)
in the same way the X kernels are packaged.
