Follow-up, I don't think this has anything to do with systemd-tty-ask- 
password-agent. I set up named-chroot on another server, in its default  
configuration, and it starts fine, and I can see that systemctl also  
executes systemd-tty-ask-password-agent, as part of starting the service.

The problem on the problematic server has to do with systemd itself. For  
some reason the service remains in "Activating" state, and systemd never  
believes that the server finished starting.

After executing "systemctl start named-chroot.service", and its start  
hanging, a minute later, "systemctl status named-chroot.service" comes back  
with:

[ syslog messages from named, unimportant ]

I can manually start /usr/sbin/named -u named -t /var/named/chroot, and it  
runs happily, but systemd does not believe that the service has started, and  
kills the entire process group, after the default 90 second timeout.

So, what's systemd's problem, here?
