The same as without any dnssec at all - edit the zonefile (including
increasing the serial number), and call 'rndc reload example.com'.  The
signed version of the zone will be updated as required - existing
signatures that are still valid won't be replaced (unless they expire
soon, etc, etc)

However, the 'allow-update' stanza makes me wonder whether you're mixing
dynamic updates with manual zonefile changes - I'm not sure whether
inline-signing can support a mixture of dynamic and manual
modifications.  If you do need to support this mixed style, Tony Finch
has a script that will generate nsupdate-style change commands from the
difference between two manual zonefiles:


If you used this, you wouldn't enable inline-signing at all, since all
changes would be dynamic.
