Ref: http://bugs.gentoo.org/show_bug.cgi?id=20974 Some packages issues warnings to the console after you emerge them. This is great - if you happen to see them. If you do an 'emerge -u world' and dont keep an eye on the screen you might miss these warnings. In the case of the url above, this results in /etc/pam.d/system-auth being overwritten "automatically", which nicely renders my system unsuable. If emerge could email the root user with these notices (its not much harder than writing to stdout after all), then we'd have some idea of what these notices actually are - its very easy to miss them if you are installing or upgrading multiple packages at once. Reproducible: Always Steps to Reproduce: 1. Make changes to /etc/pam.d/system-auth 2. emerge shadow 3. Actual Results: /etc/pam.d/system-auth is overwritten. A notice describing this is written to the console. Expected Results: As well as writing the notice to the console, it should email root@localhost (which can then be expanded via the systems alias file) or some other suitable destination with the notice.
