ACK both.
virt-dib includes the "which" program in appliance/packagelist.in.
I notice these patches don't use this program. But is it still needed?
Yes, it's needed as "host dependency" of diskimage-builder -- meaning
it is used by the parts of it, diskimage-builder proper or core
elements, which run on the host (which means in the appliance, outside
of the build chroot).
Ditto for qemu-img, curl, kpartx (and debootstrap for building
Debian/Ubuntu images).
