My original thought was just that. I wouldn't give a wetslap about some
of the einfo's but some of them are really important.
I tried per-ebuild logging, but it doesn't cut it (for me) - just too
much cruft. I guess I could grep-hack around it... anyway, notices would
limit the messages to only the ebuild (and not the entire process).

Someone said earlier (Thomas) - "Your solution would require patching
hundreds of ebuilds, just to avoid patching portage? Imho, this is a
very wrong approach."

And it has a good point to it - For users to benefit from this change,
all the ebuilds need to me fixed, changing einfo/ewarn/eerror to their
new equiv's.

Not different as such - they do almost the same thing, just that the new
functions has an additional side-effect of outputting to a notice file
(and without color, so it is logfile friendly)

Well, what are the needs beyond logging? The functionality can be added
very simply to this function. Including mailing out and the likes - All
the ebuild writer do is exactly what they do now, pass a message out.

That would be a very ugly hack (== something you shouldn't add to
portage) - It would like wrapping around portage and parsing the
per-ebuild logs... or did you mean something else?

BTW, anyone who want to test it can look for the ebuild.sh patch in my
page (http://dev.gentoo.org/~eldad/).
