Hi, Syncing today gave me this message: * Overlay eclass overrides eclass from PORTDIR: * * '/usr/portage/local/layman/desktop-effects/eclass/bzr.eclass' * * It is best to avoid overridding eclasses from PORTDIR because it will * trigger invalidation of cached ebuild metadata that is distributed with * the portage tree. If you must override eclasses from PORTDIR then you * are advised to run `emerge --regen` after each time that you run `emerge * --sync`. Set PORTAGE_ECLASS_WARNING_ENABLE="0" in /etc/make.conf if you * would like to disable this warning.
Could anyone explain me what does it mean in practice? Thanks, m.
