Gentoo users tend to do a lot of emerge's and most of the time your using the same command line options. To make life easier you can use EMERGE_DEFAULT_OPTS to set your favorite command line options as defaults.

Note: Some of the options used is only available in Portage 2.2.

The attached file contains updated copies of what I use on my production systems.

You can use this variable in make.conf or in your shells environment.

Setting it in make.conf has one drawbacks, if you set --ask it breaks things like eix-sync.

Having EMERGE_DEFAULT_OPTS being set in many different places makes it harder to maintain, so what I do is make a /etc/portage/edopts file, I can then source this file from make.conf and bash startup scripts.

Edopts example.

#!/bin/bash /etc/portage/edopts # EMERGE_DEFAULT_OPTS: --ask --update --deep --usepkg --reinstall changed-use --with-bdeps=y EDO_MAIN="--reinstall changed-use --usepkg" EDO_SHELL="--ask --verbose" EDO_CLEAN="--with-bdeps y --jobs 3 --load-average=5.00" EMERGE_DEFAULT_OPTS="$EDO_MAIN $EDO_CLEAN"

Make.conf example.

#/etc/make.conf source /etc/portage/edopts

Emerge front end.

This script works as a simple front end for emerge. It changes it's behavior based on how you call it. To activate the other modes create symlinks to this file: ln -s emerge emergex

• emerge - Runs it in a default shell user mode.
• emergey - Clean mode without options.
• emergex - Remove --usepkg and --reinstall changed-use.
• emergeu - Update the system and run some common commands to ensure a clean update.

#!/bin/bash /usr/local/bin/emerge # If the shell has EDO set we save it before sourcing edopts thats sets the default EDO if [[ -e $EMERGE_DEFAULT_OPTS ]]; then edo=$EMERGE_DEFAULT_OPTS fi # edopts is a bunch of emerge option variables and it also sets a default EDO value for use by make.conf source /etc/portage/edopts # The name we are called with effects how we run bname=$(basename $0) case $bname in emergey | mergey) # y - squickY clean emerge edo="--ignore-default-opts" ;; emergex | mergex) # x - Run without factorX, --reinstall changed-use and --usepkg that prevents us from doing a recompile edo="--ignore-default-opts $EDO_SHELL $EDO_CLEAN" ;; emergeu | mergeu) # u - Update run with kernel protection, depclean, dispatch-conf and checkrestart edo="$edo --update --deep --ask @world" ;; esac /usr/bin/emerge $edo $* # After an update @world we run some clean and check jobs. # # Protect kernels so they aren't depcleaned just after an upgrade. # # Run depclean to cleanup any unneeded packages. # # Run dispatch-conf to update configuration files. # # Run checkrestart to warn us about any running software that needs restarting. # if [[ $? = 0 && ( $bname = "emergeu" || $bname = "mergeu" ) ]]; then for a in $(qfile -Cv /usr/src/linux-*); do echo $a; done | for a in $( grep -v "/usr/src"); do name=$(echo $a | grep -Eo ".+/[[:alpha:]]+-[[:alpha:]]+") version=$(echo $a | grep -Eo "\w{1}\.\w{1}\.\w.*") grep -qs "$name:$version" /var/lib/portage/world || echo =$a done | xargs -r emergey --noreplace && emergey --depclean --ask && dispatch-conf && #revdep-rebuild && checkrestart fi

Memory compile front end.

#!/bin/bash /usr/local/bin/merge bname=$(basename $0) if ! grep /var/tmp/portage /proc/mounts > /dev/null ; then mount -t tmpfs tmpfs /var/tmp/portage -o "size=3072M" fi source $(which e$bname) if grep /var/tmp/portage /proc/mounts > /dev/null ; then umount /var/tmp/portage fi
