#68 Blocks `/docker-entrypoint-initdb.d/*` eval

[Enthalpy-AC]

A Docker network that I use has stopped working. Debugging implicates #68. Here are the logs for the relevant container when I attempt a fresh build:

The temporary server writes no text to TEMP_OUTPUT_LOG, so the until loop never falls through, blocking the DB initialization files from being read. Other processes in the network that expect the DB to actually be initialized fail.

Docker and SQL management normally aren't my responsibility, so please pardon me if I ask you to clarify the obvious during the debugging process.
