Hey folks,
just wanted to share this small script Im using
to install precompiled packages into my Gentoo-based CTs.
The idea behind this script is that there is a "BuildHost"-CT
where all pkgs get compiled and a number of more or less
equal CTs where the pkgs get installed.
One could argue that 'ROOT="<path>" emerge -K <pkg>' should be used
which is not working since the Gentoo emerge/ebuild scripts have a bug where
pkg_postinst() gets executed outside $ROOT.
cheers

# This script "emerges" prebuild tbz2 archives into a given container

# - the container family (use-flags and cflags) should be equal
# - $PKGDIR in make.conf should point to /usr/local/portage/packages
