[rancid] Fortigate additional tweaks and device filters

Wed Aug 1 19:22:42 UTC 2018

they're a combination of version & download time as i understand it.

they can be either manually updated or via a scheduled run, but for most if not all a valid support contract is required.
the reason why i prefer this info to be available is because some also change parts of the running config, though as far as i can tell this is only for autoupdating ips rules.

(example of an autoupdate 2 weeks ago)

i guess you could argue that the information thats being filtered is somewhat incomplete to begin with, since for example for antivirus you get the av definitions version but lack the av engine version. as i understand it this was due to the way how firewalls with or without vdoms parse their commands?
