Above I was just stating and pointed to what Berkeley had intended to be
done with respect to libkern, I am in no way agreeing that what they did
was a good idea.
You should know from the very early days of the 4.4 migration
of FreeBSD that I am in total agreement with you on this issue, I think
we both got pretty sick when we looked at it.
I think we should just stop building libkern, and for machines that need
routines from there add them to sys/i386/files.i386. For people doing a
new port it is nice to have these generic C functions around, but other
than that I see libkern.a as an evil thing to have done.
