Nycticorax What Justin and dbarron said...plus
I went to sudo eopkg --help:
I'm seeing a manual remove
an autoremove
the remove orphans I showed you
and a delete-cache command
I really like the rollback idea Justin had if you just want it to be pristine with no trace. I guess forensically, there will always be a trace of a package somewhere, but not splitting semantics.
Anything anyone said on this thread should achieve the goal of having updates not look for certain packages.
