Hi,
please consider the attached re-worked init script for the
authoritative server. It does away with the twisted backwards
NOTRUNNING variable which has confused me multiple times in the past.
doPC now returns a meaningful string if pdns is not running, which
eases the use of doPC in the big case, allowing the script to just
print $ret even in the "not running" case, and the pdns_running
function allows idioms like "if pdns_running; then".
Please test before committing, it is currently in the state "works for
me", and only on two test boxes
Greetings
Marc
