There's a a few -f's missing in this patch, e.g. bz2 images now fail with:

bzip2: ERROR: Function failed: do_rootfs (see /OE/tentacle/build/tmp-angstrom_2010_x-eglibc/work/beagleboard-angstrom-linux-gnueabi/systemd-image-1.0-r0/temp/log.do_rootfs.3174 for further information)
Output file Angstrom-systemd-image-eglibc-ipk-v2012.02-core-beagleboard.rootfs.tar.bz2 already exists.

A quick look suggests at least bz2 and xz images can't get rebuilt.
