[Feature Request] The ability to allow advanced custom scripts

[Jadiction]

Have you read the Important information text above

• [X] Yes i did

Describe the feature

This would allow any advanced user to modify files or have custom scripts running/ran before the server starts, allowing unlimited potential. For example, if I wanted to replace a file, or use linux sed to replace a few words in a file, this would be possible.

I would just mount /mnt/myscripts with a custom.sh file to /opt/custom/.

Then adding something like this at the top of servermanager.sh should suffice:

echo "> Checking for optional scripts"
cp -f /opt/custom/custom.sh /opt/scripts/custom.sh > /dev/null 2>&1 ||:

if [ -f /opt/scripts/custom.sh ]; then
  echo "> Found optional script, executing---"
  chmod -f +x /opt/scripts/custom.sh ||:
  /opt/scripts/custom.sh || echo "> Error thrown in optional script"
else
  echo "> No optional script found, continuing"
fi
