"Only problem that OS does not boot beyond "emergency mode"."...

But I made some progress:

- booted up into single user, bring up Ethernet, now CAN start Postgres 
but only using pg_ctl directly, does NOT work using systemctl... So 
problem is (possibly) with systemd.

Dumped base, pg_dump worked fine, dump gzipped is < 600MB, so I assume 
that somehow Postgres recovered from my (stupid) move...


BTW, pls respond only to list.
