* systemd has no way to set flexible enviroment variables,
though setting or dropping variables based on other settings is not
possible
* EnvironmentFile option in systemd can only have name value pairs no logic
* Best solution for this problem found at
http://www.mail-archive.com/systemd-devel@lists.freedesktop.org/msg05091.html
using a shell before starting the service
* move the parameter logic from sysvinit startup file to syslog-startup.conf
and source syslog-startup.conf from the busybox-syslog default file
* /etc/syslog-startup.conf is now the only config file
* works with bash and busybox-shell
* bump PRINC
