Bug#783271: When configuring custom logging in /etc/krb5.conf,, xrb5 services are unable to write to these log files as they are not, permitted in the service configuration used by systemd

[Carsten Klein]

I think that I can live with the solution proposed by Russ as it is universal 
and can be applied to all services requiring RW access to locations/files other 
than the default, thanks!
