 Replying to [comment:7 nickm]:
 > Enough authorities are now voting not to include LinkAuth=1.  I'll
 cherry-pick this commit to master.

 Please revert this change.

 When loading the consensus from disk, Tor does the protocol check *before*
 we do the consensus expiry check:
 https://github.com/torproject/tor/blob/b67f3b751a277fb940b155c0bc64f594db5549b0/src/feature/nodelist/networkstatus.c#L1871

 Therefore, any Tor that has an old cached consensus, and deploys this
 code, will restart in a loop without ever downloading a new consensus.

 Thanks to traumschule for this bug report.
