Extend Snapshotter and/or Mount to support cases where mount(2) cannot handle natively #7055
Closed as not planned
Description
What is the problem you're trying to solve
Right now containerd's snapshotter is returning Mount structs that will be passed to mount(2) as is. However it doesn't cover some use cases such as
- Extend mount package on macOS to use external snapshotters #5935
- mount: add ExtraOptions field for Mount struct #6746
- Add ability to launch containers with vm local rootfs. firecracker-microvm/firecracker-containerd#573
This issue is the place to discuss the possible options.
Describe the solution you'd like
Like out-of-process snapshotters, it would be great if we can have an option that doesn't need to modify containerd itself.
We may need to consider a clean option we could have in contained 2.0 and a mid-term option we may have in containerd 1.x.
