oh Thanks! The manpage is out of date :)
still, it didn't work with auto-serial configuration:

Error: Parsing record content (try 'pdnsutil check-zone'): missing field 
at the end of record content 'ns.example.org contact at example.org 0'

> pdnsutil check-zone example.org
Checked 21 records of 'example.org', 0 errors, 0 warnings.

Well for auto-serial you must set that value as 0 so my question being 
where the serial is kept in this special case and carried across reboot
