Read-only btrfs snapshots

Why not?

I am aware this breaks booting snapshot. Placeholder.

Correct policy should be to make read-only snapshots first and then create bootable copies for the last x desired. GUI could also have toggle to add any snapshot to the boot.

Scheme:

Head:
|
|
| snapshot (ro)
|
v

@(date) ---> @(date-writeableboot)
|
|
| prior snapshot
|
v
@(prior date) -->@(date-wb) --> @prior-date-wb+edit: changes made when booted!
