Presently Anaconda emits a record of that it initially installs, and the ks.cfg
which it used.

It would be useful to extend this a tiny bit, to help an admin who is careful to
snap a backup post install of the fresh machine, at minimal space cost, by
adding to the end of installation files laid down, something like this:

for f in $installDeviceList
    dd if=/dev/$f bs=512 count=1 of=/root/partitioning-$f.img

It then becomes possible to recover more effectively with rescue image.
