Prior chroot'ing to /target:
# mv /target/sbin/start-stop-daemon /target/sbin/start-stop-daemon.keep
# echo '#!/bin/sh' > /target/sbin/start-stop-daemon
# echo 'exit 0' > /target/sbin/start-stop-daemon
# chmod +x /target/sbin/start-stop-daemon
Now, do your chroot work, and finally:
# [ `stat --format '%s' /sbin/sbin/start-stop-daemon` -lt 200 ] && mv # /target/sbin/start-stop-daemon.keep /target/sbin/start-stop-daemon
That'll restore start-stop-daemon IFF it wasn't replaced during
something (eg. if you do your apt-get <something>, it *might* place a
newer version of s-s-d, which you want to keep, of course:)
However, if apt-get decides to install a new version of s-s-d, you're
f*cked up again...
