Package: resolvconf
Version: 1.75
Severity: important

Hallo,

since the update from version 1.74 to 1.75 is the package not correctly
initialized during system startup.
I have also installed the package systemd-sysv and so using the systemd
init system.

After a system startup, I have no resolver. I checked the files and
found that the directory /run/resolvconf is missing.

My analisys shows that the init file /etc/init.d/resolver isn't started
during system startup. That script creates the directory structure in
/run/resolvconf.

I have attached a script output of the commands that shows this error.
It After running the init script myself and then ifdown and ifup, than
the resolver works again.
