Bootable clone of Big Sur

Will we be able to boot M1 Macs from an external drive? Thanks.

From what I've read & heard lately, cloning utilities are not currently able to create bootable clones of Big Sur. Devs are working with Apple to build a solution...

Clarification: Bombitch Software (CarbonCopyCloner) says you can make a bootable clone by first cloning your boot drive (which clones the data volume) and then installing Big Sur on it. I don't recall whether this works on M1 Macs or it's only for Intel Macs.

IIRC, there are workarounds for booting from an external. The old hold-option-key-while-booting approach apparently doesn't work with M1s.
