[gentoo-user] portage cache question

[gentoo-user] portage cache question

[Covington, Chris]

Hi all,

I've recently built a new gentoo box and I noticed that the emerge
--sync is lightning fast compared to an emerge --sync on the older
boxes, even though both the new and older boxes are up to date and have
almost identical world files / versions.  Is there a way I can delete
and recreate the portage cache on my older boxes?

thanks

The post sync "metadata transfer" (equivalent to `emerge --metadata`) copies readonly pre-generated cache from ${PORTDIR}/metadata/cache/ to the writable cache which is stored in /var/cache/edb/dep/${PORTDIR}.  You can delete the whole cache with `rm -rf /var/cache/edb/*`.  After you've done that, you can repopulate it with `emerge --metadata` (`emerge --regen` is more time consuming because it sources all of the ebuilds and eclasses instead of using the pre-generated cache).

Actually, that's wrong, please don't do that.  It's `rm -rf /var/cache/edb/dep/*`.  Sorry.  :)

Oops. I've already done that. Will something go wrong now? :(

Portage should (more or less) regenerate that stuff automatically.  The worst part is probably the "global updates" bit which may take some time because portage will have no memory of the updates it has previously performed.  If you have any problems with it, join #gentoo-portage on irc.freenode.net and I'll help you.
