DESCRIPTION="Fast, dense and secure container management"
HOMEPAGE="https://linuxcontainers.org/lxd/introduction/"
EGO_PN_PARENT="github.com/lxc"
EGO_PN="${EGO_PN_PARENT}/lxd"

# The source is repackaged using a script at:
#   https://dev.gentoo.org/~stasibear/lxd_repackage.py
# This is necessary because go's native package management assumes
# that a build starts with checking out many git repositories, often
# from HEAD.  This provides no way to build the same code repeatably,
# and anyway portage requires that fetching is only done from SRC_URI.
# The only sane alternative I've seen is in the consul ebuild, which
# is more transparent but raises other questions.
