Startup delayed by usermod for several minutes

[someCynic]

While starting up the following command is run:

usermod -o -u {UID} abc

This command takes about 5 minutes to run on a raspberry pi 3 model B+, I suspect because it's making changes to Plex's Library folder.

This looks similar to the issue in linuxserver/docker-plex fixed on 11.01.07, given the changelog: "Use Plex environemt variables from pms docker, change abc home folder to /app to alleviate usermod chowning library folder by default (thanks gbooker, plexinc)."

The fix was to change the abc user's home to /app:

echo "**** ensure abc user's home folder is /app ****" && \
usermod -d /app abc && \
