[ixpmanager] Issues with MRTG in Ubuntu 18.04

[Mauricio Oviedo]

Hi Nick,

Thanks for the information.

At the end it worked correctly after creating a file called
/etc/tmpfiles.d/mrtg.conf
with the following contents:

d /run/lock/mrtg 1777 root root

Now MRTG starts fine after a reboot.

Thanks for your help.
