I have asked on IRC and nobody seemed to know if emerge had a history. If not then it would be nice to have a logfile that told: * What was installed (uninstalled) * Versions of (un)installed stuff * When it was (un)installed This is tremendously usefull for tracking down bugs that you know was not on you system 14 days ago but that seems to be there now. In principle it could just start out as: date >>/var/log/emerge-history echo $* >>/var/log/emerge-history But a more sofisticated logging would ofcourse be better.
Another use for this is a question I just saw on IRC: How long time does it take to compile gcc? This could be answered by reading the logfiles (at least I could tell how long it took on my machine).
im pretty sure a history function doesnt exist, and as for the 2nd comment, its already been filed as another bug ;)
