We changed the rules so intrinsic tags are inherently blacklisted across all sites.
(an intrinsic tag is "apple" on apple.se, "wordpress" on wordpress.se, etc etc etc etc. See https://unix.meta.stackexchange.com/a/514/5132 for some more details.)
We can remove "linux" as an intrinsic tag -- "unix" is also intrinsic here -- but this means you will get questions tagged "linux" migrated here without the tag removed.
