On one server Unmaintained Gentoo packages OID: 1.3.6.1.4.1.25623.1.0.24017 is causing a huge list of false-positives. I suspect the check compares the installed package versions to the ones available via the portage package repository.
Since this server is the one with the most recent Gentoo installation I suspect the checks have hardcoded paths.
It would be nice to have the checks fixed to take the new default locations into consideration as well, or even better expand the logic to read and parse the output of emerge --info for this.
Due to the fact that many repros can mix up a lot of different things. A “portage” location could help, but with the up-to-date Gentoo there is nothing that blocks you under profile 17.1 still maintain it under /usr/portage so you can use a shared profile via nfs across profiles and machines.
I’m aware that I can change the default location back to the “old” way of /usr/portage however in my opinion the check should work for distribution default configurations and should take the (recent) change to that into account.
