LaunchDaemon starts too soon — how to work around?

I have a LaunchDaemon that starts Docker, but the files Docker needs to run are on a filesystem that takes another 15–20 seconds to mount.

Consequently, I have to quit the stalled Docker instance and restart it manually.

I’m trying to figure out a better way to have Docker start after the file system mounts. I have two main thoughts.

1. Have Docker’s LaunchDaemon wait for 30 seconds or so before starting.
2. Stop the LaunchDaemon from running at load and have a separate daemon count to 30 before invoking Docker’s LaunchDaemon

Any thoughts or suggestions would be fantastic!
