I'm very open to the idea, after we agree on how to approach it.
Maybe I'm missing something though (I almost certainly am), but do we really
need a 'microdpkg-deb'? Wouldn't just 'microdpkg' be enough? When we go to
install the base system, we really just want to unpack the .debs and drop them
into place. For this to take place we can do something like the following:
#!/bin/sh
# Lame 5 minute micro-dpkg shell script...
# Erik Andersen <[EMAIL PROTECTED]>
if [ -z "$1" ]; then
echo "usage: udpkg packagename.deb"
exit 1;
fi;
FOO=`basename $1`
PACKAGE=`echo $FOO | sed -e "s/_.*//g"`
ROOT=/
DPKG_INFO_DIR=/var/lib/dpkg/info/
#For debugging only
DPKG_INFO_DIR=/tmp/fff/info
ROOT=/tmp/fff
mkdir -p $DPKG_INFO_DIR
ar -p $1 data.tar.gz | zcat | (cd $ROOT ; \
tar -xvf - > $DPKG_INFO_DIR/$PACKAGE.list)
ar -p $1 control.tar.gz | zcat | (cd $DPKG_INFO_DIR ; \
tar -xf - )
if [ -f $DPKG_INFO_DIR/postinst ] ; then
mv $DPKG_INFO_DIR/postinst $DPKG_INFO_DIR/$PACKAGE.postinst
fi
if [ -f $DPKG_INFO_DIR/postrm ] ; then
mv $DPKG_INFO_DIR/postrm $DPKG_INFO_DIR/$PACKAGE.postrm
fi
if [ -f $DPKG_INFO_DIR/preinst ] ; then
mv $DPKG_INFO_DIR/preinst $DPKG_INFO_DIR/$PACKAGE.preinst
fi
if [ -f $DPKG_INFO_DIR/prerm ] ; then
mv $DPKG_INFO_DIR/prerm $DPKG_INFO_DIR/$PACKAGE.prerm
fi
if [ -f $DPKG_INFO_DIR/md5sums ] ; then
mv $DPKG_INFO_DIR/md5sums $DPKG_INFO_DIR/$PACKAGE.md5sums
fi
if [ -f $DPKG_INFO_DIR/control ] ; then
mv $DPKG_INFO_DIR/control $DPKG_INFO_DIR/$PACKAGE.control
fi
exit 0;
If we really wanted to be cool, we could even use parse the control file, check
the depends and the md5sums and such. I suspect doing that is overkill though.
