-Subject: [PATCH 1/5] gpt: disable gpt partition attribute 55 check
-
-Endless OS uses flag 55 to mean a partition should be auto-grown, and
-to identify Endless OS partitions.  Both of these meanings of flag 55
-are specific to Endless OS though, so it doesn't make sense for
-installing other operating systems.

-Subject: [PATCH 4/5] finished: don't run eos-diagnostics
-
-This has to be installed separately from eos-installer, and we don't
-currently do that for the Spectrum installer.  If there was an error,
-eos-installer would try to run it, and then display an additional
-error message about not being able to find it on the error screen.
