I'm currently hacking on PicoBSD and have a couple of ideas that
I'd like to run by you all before I commit them:
* I believe that it make sense to build the PicoBSD sources in
their own object directory, /usr/obj/picobsd/${TYPE}/usr/src,
instead of over the top of /usr/obj/usr/src...? Quite often the
build options of programs that we want on a PicoBSD disk are different
from those in the main system.
* One of the main problems with PicoBSD at the moment is that we can't
pass compile flags to programs on a per program basis. This is
because of missing functionality in crunchgen. In particular this
means that we can't actually selectively compile out parts of
programs that we don't want on a per config basis. A case in
point is user-ppp. This has become very large over time as it's
been able to deal with more and more things, most of which aren't
required for the dial picobsd config for instance. On the
otherhand it should be possible to compile in ATM support, for
instance, if we want it.
I've got a work around for this. It involves adding an extra
configuration file to the crunch1/ subdirectory for a particular
type. i.e:
genius% pwd
/usr/src/release/picobsd/build
genius% cat buildopts.inc
# $FreeBSD$
OPTS= -DNOPAM
ppp_OPTS= -DNOKLDLOAD -DNOINET6 -DNONAT -DNOATM -DNOSUID -DHAVE_DES -DNORADIUS - DNOI4B -DNONETGRAPH
#end
OPTS is added to every program that is built, and the progname_OPTS
are just added to that program.
This allows much more customisation. I'll probably remove the generic
${CRUNCHFLAGS} from the build/ scripts and replace them with local
customistations, if that makes sense to people here.
