Description cwillisf 2002-07-16 03:01:04 UTC

Hopefully this hasn't already been listed, but here goes...
I think it would be cool to have an option to emerge to make it run through the
currently-installed packages checking if changes in the USE flags would affect
that package, and if so re-emerge it. That way if you installed vim, then added
"gnome" to your USE flags, emerge would rebuild the vim package so that you now
had gvim. I know "emerge -e world" will do this but isn't that kind of like
swatting a fly with a bus? ;)
This could also be extended to notice changes to CFLAGS / CXXFLAGS, but that
doesn't seem very useful to me since it seems that would end up doing 99% of an
"emerge -e world" anyway... so if that were done it would probably need to be a
separate flag from the one to notice USE changes...
