possibility of transferring the system in a USB Hard Disk

[TheOldPresbyope]

We could prolly do that type of partition magic but IME it's never a good idea to put user data on the same media that contains the OS.

I don't disagree. Any mistake on the part of the user and their music partition is toast. Most packaged NAS systems I've tried keep the media disk(s) separate for the same reason.

In addition to the safety factor gained by using a separate boot/root card, there's the convenience factor of being about to move it between computers for flashing, testing, etc. (ETA - I suppose one can argue this is true for a larger USB HD/SSD as well.) This item already can be a thumbdrive rather than a uSD card.

But, hey, this is DIY. If a user wants a double-edged razor they can have one. They just don't get to complain about any accidental blood letting
