Just tried it now. The boot seems _extremely_ slow and invited 
at least some intervention (manually typing run bootcmd_usb0
at the u-boot prompt) but it did come up multi-user. It is able
to function as a terminal server to nemesis.zefox.com, so I'll
just watch it for a while. The netmap has been updated to reflect
the change to config.txt.

An aside, none of the seven hosts has dropped a tip session over
the past day or so, except when taken down intentionally.

For now powerd is off on all FreeBSD hosts, the Pi4 workstation
is running something called upowerd as always. I'm thinking to
eventualy re-start powerd on only a subset of hosts in hope that 
will make behavioral differences more obvious.

Thanks for your help!
