Recompile your WSL2 kernel - support for snaps, apparmor, lxc, etc.
Yes, I've done this, and yes, it works. It is, however, entirely unsupported and assembled through reasonable guesswork, so if you try this and it explodes your computer, brain, career, relationships, or anything else, you agree that you take sole responsibility for doing it, that I never claimed it was a good idea, and that you didn't get these instructions from me .
Also note: I have done this with Debian Stretch. While one kernel ought to fit all, some of the packages you need to build it may be different. Adapting to other distros is up to you.
