I accidentally checked in "ectool-patches-of-unclear-provenance.patch",
which was never used in any way by the build expressions.
This file contained my local patches to a very old version of
ectool, some of which came from Debian and some of which I wrote
myself. The `ectool.nix` expression uses a newer version of ectool,
which has upstreamed the relevant changes from Debian. So those
patches no longer need to be carried. The other patches delete
functionality which I don't need, but other people might, so those
patches won't be included in ownerboot.
