* use 127.0.1.1 under debian (since it's the default there)
* also set the IPv6 loopback address (::1) since some tools tries to
AAAA resolve the hostname (for example sendmail)
* ensure proper /etc/hosts format through postinst-script (hostname as
last entry)
Do not reexec systemd when running version is the same as installed
binary. Apparently reexec causes some race condifions, which result in
assertion fail in systemd.
SystemD version can differ from initramfs one (which is build in dom0
build environment), so reexec it at startup.
This fixes systemd-212 archlinux issue.
Introduce proxy service, which allow only http(s) traffic to yum repos. The
filter rules are based on URL regexp, so it isn't full-featured content
inspection and can be easy bypassed, but should be enough to prevent some
erroneus user actions (like clicking on invalid link).
It is set up to intercept connections to 10.137.255.254:8082, so VM can connect
to this IP regardless of VM in which proxy is running. By default it is
started in every NetVM, but this can be changed using qvm-service or
qubes-manager (as always).
