kldxref(8) in what you're looking for.
I personally recommend creating diskless roots by using install targets
rather then copying files around by hand. For instance the following is
a script I use to create roots for testing (the ports stuff isn't
necessicary of course, but I included it because it's somewhat
intresting and some of the issues are non-obvious):
---<cut>---
#!/bin/sh
src=3D/usr/home/brooks/aero-p4/fellowship/roots/freebsd/5.2-CURRENT
dest=3D/usr/diskless/5.2-CURRENT.deptest
kernconf=3DNODE
ports=3D/usr/ports
# Rebuild the source
#cd ${src}
#make buildworld
#make buildkernel KERNCONF=3D${kernconf}
# delete the old setup
#rm -rf ${dest}
#chflags -R noschg ${dest}
#rm -rf ${dest}
# install a new world
cd ${src}
mkdir -p ${dest}
make DESTDIR=3D${dest} installworld
cd etc
make DESTDIR=3D${dest} distribution
cd ..
make DESTDIR=3D${dest} KERNCONF=3D${kernconf} installkernel
# install a copy of ports
# This copy of ports is assumed to be up to date with a correct INDEX.db fi=
le.
cp /etc/resolv.conf ${dest}/etc/resolv.conf
mount_devfs devfs ${dest}/dev
#cpdup -i0 -vv /usr/ports ${dest}/usr/ports
mkdir -p ${dest}/usr/ports/
rsync -av --delete --exclude=3DCVS /usr/ports/ ${dest}/usr/ports/
if [ ! -d ${dest}/var/db/pkg/portupgrade-* ]; then
chroot ${dest} pkg_add -r portupgrade
fi
#chroot ${dest} portupgrade -a
chroot ${dest} portinstall -M BATCH=3Dyes ganglia-monitor-core sge diskmark=
