* plugin/file: make non-existent file non-fatal If the zone file being loaded doesn't exist *and* reload is enabled, just wait the file to pop up in the normal Reload routine. If reload is set to 0s; we keep this a fatal error on startup. Aslo fix the ticker in z.Reload(): remove the per second ticks and just use the reload interval for the ticker. Brush up the documentation a bit as well. Fixes: #2951 Signed-off-by: Miek Gieben <miek@miek.nl> * Stickler and test compile Signed-off-by: Miek Gieben <miek@miek.nl> * Remove there too Signed-off-by: Miek Gieben <miek@miek.nl> * Cant README test these because zone files dont exist Signed-off-by: Miek Gieben <miek@miek.nl>
