probably better replace this with a sudoers.d file remove afterwards. Otherwise this test leaves side effects.

it does intentionally NOT do a sudoers.d (there are a few tests before that testing the snippets included); the last stage is to test modifying /etc/sudeors.

the sed part being done is being reverted in the post_run_hook already (the only difference to 'base setup' is that /etc/sudoers is in place - a copy of /usr/etc/sudoers; something that can be accepted IMHO)

IMO it should revert this as well

Added a marker (/tmp/sudoers.copied) when copying it and when this marker is present, remove the file at the end again (the sed revert is overkill there, but making the change least intrusive to not break SLE)
