I do not see a lot of readability improvement by introducing those two functions and reversing the order of checks for OVERPASS_MODE and -f /db/init_done. Can you elaborate, why you think this improves readability?

The refactor itself wasn’t actually "the goal". it was needed so I could introduce the logic change (moving the OVERPASS_STOP_AFTER_INIT check after the init_done guard) in a clean, isolated commit. Breaking it out into functions made the flow easier to rearrange without duplicating code, and kept the "fix commit" focused more on behavior.

Basically the fix introduced required refactors, and I split the refactors out of the fix commit, to keep the scope solely to the fix.

I'm not convinced that this change was necessary. What is the reason in changing:

What is the point of this check? Since only "init" or "clone" are allowed values this if is always true.

if [[ "${OVERPASS_STOP_AFTER_INIT}" == "false" ]]; then
echo "Overpass container ready to receive requests"
else
echo "Overpass container initialization complete. Exiting."

Can we just move this one fi below, into the main, just before envsubst is called, and this will simplify the whole script, as we will need to check only once?

fi

# shellcheck disable=SC2016 # ignore SC2016 (variables within single quotes) as this is exactly what we want to do here
envsubst '${OVERPASS_MAX_TIMEOUT}' </etc/nginx/nginx.conf.template >/etc/nginx/nginx.conf
