On the contrary, it's very little work: just a simple tar command.
But the tarball will eat loads of disk space when not excluding
distfiles.

But he can't: the ebuild is gone. That is the case we're trying to
solve here: he has emerged a newer version of a package, finds it
doesn't work correctly, wants to go back to the previous version,
but seess that that version is gone. How to get it back? One way
is to get it from viewcvs on the net. Another way is to keep a copy
of all the ebuilds yourself. It's a big waste of space, but it is
simple, no searching on the web required.
The best way, of course, is to use the binary package thing. Mark:
add EMERGE_DEFAULT_OPTS="-b" to your /etc/make.conf. This will
tell emerge to also build a binary package for every package that
you emerge. Whenever you find that an upgrade of some package was
unfortunate, do an 'emerge -K =package-x.y.z' with the exact
version number you want to restore, and done. No manual tarring
and untarring required, emerge does it all.

Benno,
Now that is an interesting solution, especially for my Myth boxes
which do not get touched for 6 months to 1 year. I've had problems
with Gentoo devs getting rid of older ati-drivers, mythtv to some
small extent ivtv a long time ago. Anyway, if binary packages were
built and stored in some reasonable location then I could probably
prune out things that I'm not worried about, like fluxbox, etc., but
keep the critical stuff like Myth, video drivers.
I'll check it out, as well as Bo's FEATURES=buildpkg comment.
I wonder if -b could be put in one of the /etc/portage/package.XXX
files so that it could be done every time for ejust specific packages?
Thanks for the idea!
Cheers,
Mark
