Can I recapitulate the routine? So it should be something like that: layman -S emerge --sync emerge -DuN world emerge @preserved-rebuild emerge --depclean revdep-rebuild eclean distfiles -t=2w eclean packages -t=2w dispatch-conf elogv
Right? But this script could not be run automatically because of dispatch-conf that needs user intervention.
