There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
Recently a user wanted to be sure that Ethernet over USB worked, which leads to these:
- What drivers/kernel objects are loaded on the 'live' pseudo-install?
- A step by step to troubleshoot the 'live' pseudo-install such as to enable other features or devices.
- Internet connection sharing is not specifically named and does not seem to be described.
- How to setup a ether to wifi hotspot/sharing is also not mentioned.
Freebsd handbook 32.3.5 describes this configuration but its a reasonable expectation for a laptop to be able to share out its wifi while attached by ethernet cable.
