RADVD config empty after update to 16.7.12

[Droppie391]

Last noght, we updated our 2 OPNsense firewalls (CARP) to 16.7.12
On the pimary, unbound did not start from itself, a manual start worked.

Also on the primary, radvd did not start (on the secondary machine all is fine)
We found that the radvd.conf file in /var/etc/ was empty, in contrary to the same file on the secondary machine.
Changing settings in the advertisement or dhcp6 server page did not create any entries to the file (on the secondary, it did)
We then copied the contents of radvd.conf from the secondary to the primary and were able to start the service but any mpdification from the webinterface, empties the file again.
We have not enabled the dhcp6 server, only radvd as unmanaged service.
Everything worked until the update.
What concerns us, is the fact that it works on one machine but not on the other although they are both on the same sw level.

Hi Droppie,

Last changes to radvd were on 16.7.9, so this is odd indeed.

It could be a problem with the installed files, best to force a reinstall of the "opnsense" package from the firmware GUI page and a reboot before continuing to look for clues.


Cheers,
Franco
