Package: openvpn
Version: 2.3.4-5
Severity: important
Dear Maintainer,
A system booting under systemd will hang indefinitely when an interface
is configured via openvpn and marked "auto" in interfaces(5), e.g.:
auto vpniface
iface vpniface inet manual
openvpn somevpn
(with AUTOSTART="none" set in /etc/default/openvpn)
What happens is that when the networking.service runs 'ifup -a', the
script /etc/network/if-up.d/openvpn calls 'systemctl start openvpn@somevpn'
but because the openvpn@.service unit has an implicit dependency on
basic.target, and because basic.target is not yet active while
networking.service is starting, systemd deadlocks with the following
message displayed on the console:
[ *** ] A start job is running for LSB: Raise network interfaces.
I was able to avoid the problem by adding this directive to the
openvpn@.service unit file:
DefaultDependencies=false
This breaks the dependency loop on basic.target, and allows the openvpn
interfaces to be brought up during boot. However, I am not certain whether
this is entirely correct and appropriate.
Please examine the problem and this possible solution, and adjust as
appropriate.
Kind regards.
