cmd: expose overlayfs extraction support #574

Open

Description

@cyphar

Most of the support code already exists (especially once we merge #572) but there are some questions of how the API should work for this kind of extraction. For one thing, the current rootfs + mtree model doesn't really work so we would need to rework a lot of that logic as well as come up with a nice way for runc run to "just work" with an auto-setup overlayfs mount...

    A question I've been mulling around is whether we should have umoci mount to mount the overlayfs, or just generate a generic mount.sh script for admins to use, or just leave it up to users?

    It would be unfortunate for us to create a bundle where the rootfs is missing or has no data because the user didn't know they have to mount the overlayfs themselves...
