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 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 --newuse --update @world)
  • rebuilds any packages depending on stale libraries (using emerge @preserved-rebuild)
  • updates any old perl(1) modules (using perl-cleaner --all)
  • updates any old python(1) modules (using python-updater)
  • 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)
  • deploys new kernel from staging (if desired and available) (using buildkernel --copy-from-staging)
  • updates environment settings (as a precautionary measure) (using env-update)

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 on the Gentoo wiki (forthcoming).
