genup
Tool to update the Portage(5) tree, all installed packages, and kernel, under Gentoo Linux.
Description
genup is a utility intended to simplify the process of keeping your Gentoo system up to date. When invoked, it automatically performs the following steps, in order:
- updates Portage tree (and active overlays), and syncs eix(1)
(using
emaint sync/eix-sync) - removes any prior emerge(1) resume history
(using
emaint --fix cleanresume) - ensures Portage(5) itself is up-to-date
(using
emerge --oneshot --update portage) - updates all packages in the @world set
(using
emerge --deep --with-bdeps=y --changed-use --update @world) - rebuilds any external modules (such as those for VirtualBox)
(using
emerge @module-rebuild --exclude '*-bin') - rebuilds any packages depending on stale libraries
(using
emerge @preserved-rebuild) - updates any old perl(1) modules
(using
perl-cleaner --all) - resolves clashing config file changes (in interactive mode)
(using
dispatch-conf) - upgrades the kernel if possible (to staging, in /boot)
(using
buildkernel --stage-only) - removes unreferenced packages
(using
emerge --depclean) - fixes missing shared library dependencies
(using
revdep-rebuild) - rebuilds any packages depending on stale libraries (again)
(using
emerge @preserved-rebuild) - removes any unused source tarballs (if desired)
(using
eclean --deep distfiles) - deploys new kernel from staging (if desired and available)
(using
buildkernel --copy-from-staging) - updates environment settings (as a precautionary measure)
(using
env-update) - runs any custom updaters in /etc/genup/updaters.d
The genup utility can be invoked in non-interative (default) or interactive mode (see the --ask option in the manpage). Non-interactive mode is suitable for use in a scripted invocation, for example as part of a nightly cron(8) job.
Installation
genup is best installed (on Gentoo) via its ebuild, available as part of the sakaki-tools overlay. Full instructions are provided as part of the Sakaki's EFI Install Guide tutorial, on the Gentoo wiki.
