thank you for directing me there - i did not recognize that
wg-quick adds functionality.

using it gives some troubles here with DNS. i use a home grown
script for resolveconf (i do not change the file
/etc/resolv.conf but use dbus to tell dnsmasq the current
nameserver). wg-quick issues a

	[#] resolvconf -a tun.wg0 -m 0 -x

which seems to be wrong, the manpage resolvconf(8) states that the
this parameter is

	interface[.protocol]

why is "tun." prepended?

the command is issued before the routing is configured.
shouldnt the DNS configuration be applied after routing
changes?
