I once used the following trick to create a simple partition table (dangerously
dedicated?) inside a makefs built image:
makefs -b '10%' -o label="${LABEL}",version=1 base.ufs R/
bsdlabel -w -B -b R/boot/boot -f base.ufs
_label_file=$(mktemp labelXXXXXX)
bsdlabel -f base.ufs | sed -e '/ a:/s/unused/4.2BSD/' -e '/ a:/s/ 16 / 0 /' >
${_label_file}
bsdlabel -R -f base.ufs ${_label_file}
rm -f ${_label_file}
I would be more happy to have gpart-in-userland :-)
