That's a bit surprising. systemd should add /usr/sbin to PATH. A minimal
test case

# cat /etc/systemd/system/env.service
[Unit]
Description="dump env"

[Service]
ExecStart=/bin/sh -c "env"

# journalctl -u env
-- Logs begin at So 2016-05-08 15:58:46 CEST, end at Sa 2016-07-16

Jul 16 22:46:15 pluto systemd[1]: Started "dump env".
Jul 16 22:46:15 pluto sh[28592]:
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
Jul 16 22:46:15 pluto sh[28592]: LANG=en_US.UTF-8
Jul 16 22:46:15 pluto sh[28592]: PWD=/



So for some reason $PATH is reset. I wonder where that happens.
I noticed that postfix's resolvconf in jessie uses
/etc/init.d/postfix instead of service postfix, so doesn't run into this
issue.

So, it seems to me as something resets PATH within resolvconf.
If that is true, then this should also affect the old sysv init script
for unbound. Is this actually still working?
