Re: [gentoo-soc] rfc: reducing the time of "Calculating dependencies" phase project.

[James Cloos]

As someone whe often does edit ebuilds in overlays (very occasionally in
/usr/portage, too), having to run something to update the cache for said
overlay is OK.

But it *must* update just the cli-specified overlay(s), w/o having to go
through and update everything every time it is run.

For comparison, my primary workstation, with several overlays, takes
several minutes to do a dep.  Even with a hot cache.  Improving that to
something reasonable is the single most important change portage can get.

Also, if /var/db/pkg is to be cached, the existing /var/db/pkg layout
should remain as a backup, so that the cache of what is installed can
be restored easily should it ever get corrupted.  Portage can update
that cache after updating the /var/db/pkg/ tree.
