Yup and make sure you keep a backup on a separate machine. I used to just keep flash backups on the array with the rest of my stuff. You can still get to it without unraid mounting the main file system but it’s another level of annoyance you don’t need when your system is down.

I don’t really mind the system contacting unraid mothership. It’s a way to prevent pirates and sneaky types from ruining it for all of us paying users. Maybe when they stop doing that, license management gets easier.
