Should the container rootfs take the input Type instead of hardcoding ext4?

https://github.com/firecracker-microvm/firecracker-containerd/blob/e6c7a36c34f827a4229d4c898f9b406e9742d7a5/runtime/service.go#L1186

I'm specifically interested in supporting XFS-based snapshots for the container rootfs. I know other drives can be XFS, is there a reason that the container rootfs has to be ext4? (Assume I build my kernel with XFS support)

Thanks!

Start at runtime/service.go around line 1186 and trace how the container rootfs type is selected and passed into the service. Check the existing rootfs and snapshot handling, then determine what behavior and tests would demonstrate support for XFS-based snapshots instead of a hardcoded ext4 type.
