dev-db/etcd: bump to 0.4.6
baselayout: add polkitd user
polkit: pull in current upstream ebuild
polkit: fix compiling in an alternate sysroot
systemd: add nls use flag

When enabling policy kit there appears to be a build race condition in
the generation of updating translations in policy files. There is a nls
configure flag in systemd now, we don't need translations.
polkit: fix config install paths, use systemd-tmpfiles

All configs should be installed to /usr and tmpfiles should be used to
create and fix directory permissions instead of the ebuild's postinst.
profiles: enable polkit
systemd: prune old systemd 212 ebuild
systemd: grant networkd access to set transient host name
coreos: install lsusb and lspci in base system
Merge pull request #781 from marineam/polkit

Add polkit and support for DHCP host names
Merge pull request #782 from marineam/utils

coreos: install lsusb and lspci in base system
profiles: rebase onto Gentoo's hardened profile

The default 10.0 is deprecated and removed upstream. Also, instead of
twiddling the hardened flag we should just use the hardened profile.

As part of this the host SDK no longer has multilib enabled, it isn't
actually needed for anything anyway.
profiles: disable static binaries

Left over from some odd behaviors of the ChromeOS build systems.
hard-host-depends: remove google-breakpad

This package does not build in the SDK after removing multilib support.
We don't actually need it, kill it.
sys-kernel/coreos-kernel: enable ipmi support
Merge pull request #784 from crawford/ipmi

sys-kernel/coreos-kernel: enable ipmi support
docker: sync ebuild with latest version in Gentoo

Most of the change here isn't significant except for the compilation
fixes for compiling with a hardened compiler. This was not an issue
previously because the SDK's cross compiler wasn't hardened.
