i have test a lot with file attributes. not needed. magicMirror is not linux, its javascript. only the copy command and pm2 command in the exec function must linux conform. in the pm2 log you have sometimes error messages, but that comes from linux. so you have right, without x-flag its not executable, but MagicMirror ignore file attributes.
now i can cange all my configs with remote-control. for the moment i am finished this module. maybe later i have a new idea, ha,ha.
