I decided to migrate to busybox on my embedded Debian to save a some space. You can either do this on the running system or you can do it while building it in the chroot environment.
apt-get install busybox
cd ~/
vi setuplinks.sh
#!/bin/bash
which busybox &>/dev/null
if [ $? != 0 ]
then
echo "Busybox is not present in the working path."
exit 1
fi
oIFS=$IFS
IFS=" ,
"
export BB=`which busybox`
for i in `cat busycmds`
do
if [ $i == "busybox" ]
then
continue
fi
which $i &>/dev/null
if [ $? == 0 ]
then
ln -f $BB `which $i`
ls -i `which $i`
else
ln $BB /usr/bin/$i
echo make $i
fi
done
IFS=$oIFS
vi busycmds
