How to "wrap" root "/" in subvolumes?

[Денис Харцхаев]

With script "nand-sata-install" I moved root "/" to hdd on the filesystem "btrfs" and the "Boot" partition stayed on "SD" card.
Questions:
1. How can I to "wrap" it in subvolumes so that I can use btrfs snapshots?
2. It is possible to move the "Boot" to "HDD" too?

 

PS -my orange pi 3 has no emmc

I don't think the OPi3 can boot from USB directly. So you'll always need an sd-card for initial boot.

Too bad you don't have eMMC. It is a great feature to have on these OPi's.
