Speaking of which, I'm somewhat of a NetBSD newbie, but
firstly: is there a better way to "release" smaller distributions. For 
my embedded
box, I only have 30MB of Compact flash, so can't sysinst anything
without modification. The distrib/set is too course for embedded. I
notice the lists have package names in them but I can't tell if these
can be used or not. As a quick hack I added:
 if [ -f dist/${setname}_obsolete ]; then
 >               cp dist/${setname}_obsolete $SDIR/olist.$setname
 >               # we want file only in ilist
 >               comm -23 $SDIR/ilist.$setname $SDIR/olist.$setname 
 >       else
 >               mv $SDIR/ilist.$setname  $SDIR/flist.$setname
 >       fi
to distrib/sets/maketars and extended the obsolete lists for my platform 
to exclude
stuff I don't want in the sets (but nfs mount back to the distribution 
for debug)
Secondly, MACHINE/MACHINE_ARCH is insufficient for the setups
such as "evbarm" and "evbppc". evbarm can use "machine_cpu" as a 'dimension'
since its one architecture with two different cpus but evbpcc is many 
with the same cpu. perhaps a MACHINE_BOARD or being able to specify
say evbpcc.walnut as MACHINE or tie in "conf" more formally. wrote:
