Thanks for writing the blog post; it was a fascinating read! I was curious about a couple of things: * Have you considered future extensions where you can start the VM before you completed the FS copy? * You picked XFS over ZFS and BTRFS. Any reason why XFS in particular? * You casually mention that you wrote 'otterlink', your own hypervisor. Isn't that by itself a complicated effort worthy of a blog post? Or is it just mixing and matching existing libraries from the Rust ecosystem?

Not the author, but: > Any reason why XFS in particular? XFS is still the default filesystem of choice for many enterprise systems. For instance, Red Hat states in their manual [1]: In general, use XFS unless you have a specific use case for ext4. There are good reasons to choose other file systems, but if you just want good performance on simple storage, XFS is a pretty good default.

Also: did you consider using LVM snapshots?
