Thanks for the clarification. I note that in
src/distrib/i386/floppies/kc-common/Makefile.inc, disklabel is still
used. Now for a weird observation: when sticking the inst12E.fs floppy
in at the "Insert filesystem" prompt when booting from a 12E kernel
copy floppy, I kept getting "Unable to mount root" errors. Having
rebuilt a kernel with #define DEBUG 1 as the first line of
src/sys/kern/vfs_subr.c cured it. 1) I don't understand why, 2) I
didn't undefine it at the end, so it may have had an effect
elsewhere...

Cheers,

 Patrick
