I had the phd daemons crashed (the Daemon console reported them yellow, with This daemon has not reported its status recently. It may have exited uncleanly.), after which phd status lists them as active, so is_running returns true, and the script refuses to (re)start them. I seem to have fixed it by using --local flag in the phd status command inside is_running. With that argument, phd status responds There are no running Phabricator daemons., so this script starts them correctly, when asked to.

…or maybe not. Now even phd status --local lists those dead daemons, only marking them with <DEAD>. Not sure what is the proper way to detect running daemons.

Even with the --local modification it seems to only want to spin up one of the daemons on boot. The taskmaster one to be precise. It will only start them all if you restart it.
