Description

Is your feature request related to a problem? Please describe.
I like to use snapshot for linux when I install new software or do some dangerous for the system,so I can roll back it.

But I don't know if wsl2 can support btrfs or other CoW filesystems.

Describe the solution you'd like

as same as the title

Describe alternatives you've considered
Well, the alternative is to use chroot , but I think it's troublesome.
