[nsd-users] [PATCHES]: Don't check zone files modification after NSD start or after receiving HUP signal.

[Robin Hack]

Hi.

I am sending a set of patches, which add options to a configuration file:
diable-zonefiles-check:yes/no - enable/disable check of zone files
modification after NSD start
disable-zonefiles-check-hup: yes/no - disable/enable check of zone
files modification after receiving HUP signal

Our servers hold over 150 000 zones and it is not required big disk
operations (call stat() on each file) after NSD start or receive HUP
signal.
Maybe someone will like these configuration options.

Changes and upgrades are welcome :).

This patches and other patches are also available on my github.

Maybe they will be interesting and inspirating for someone.

Best regards,
Robin Hack
