kaithar/gentoo-base repository overview

This is a stage3 import with some extra tweaks to make it a decent base image. I will, at some point, try to make it smaller by purging some of the bloat. It isn't made via Dockerfile currently, I need to decide what I'll do about that.

Some important notes:

Volumes to mount:

/usr/portage:/usr/portage:ro
/container/gentoo/packages:/packages
/container/gentoo/distfiles:/distfiles 

The first one should be adjusted if you're not running a gentoo host system.

In make.conf we set:

• To prevent portage trying to download files here but use them if they're there PORTAGE_RO_DISTDIRS="/usr/portage/distfiles"
• Where it should download to if they aren't there, this should definitely be volume mounted DISTDIR="/distfiles"
• We build packages to speed rebuilds PKGDIR="/packages"
• For those packages EMERGE_DEFAULT_OPTS="-kb"
• the latter one allows for concurrent packages for the same version of a package. See man page for make.conf FEATURES="buildpkg binpkg-multi-instance"

Commands...

• Don't need cgroups here sed -i 's/#?rc_controller_cgroups=".*"/rc_controller_cgroups="NO"/' /etc/rc.conf
• This is to talk gentoo in to not looking for kernel related things sed -i 's/#?rc_sys=".*"/rc_sys="docker"/' /etc/rc.conf
• Because these as files is lame mkdir -p /etc/portage/package.accept_keywords /etc/portage/package.use /etc/portage/package.mask

Use flags set...

• This is to fix an issue I was having with crypto conflicts on a container that inherits this one dev-vcs/git -gpg

Final emerge

• In addition to trying to make this fully updated, we install a few packages that come in handy for building and working within most images. emerge --newuse --deep --with-bdeps=y @system @world monit tmux app-misc/screen dev-vcs/git vim nano gentoolkit
• Make sure we kill off the extra junk emerge --depclean
