Now this is WHY I love UNIX and UNIX-likes, the fact you can chop and change core components like the Kernel, Userspace, Init, etc. and (within compatibility limits i.e. MUSL/GLIBC) run a hybrid system like Chimera.

Would I run Chimera as a daily-drive? Probably not. Is it cool that someone can? Absolutely!

When I last looked a few years ago, there were some efforts and successes in the far East doing "chimera Windows", mostly based on running an older userland (like XP) on a newer kernel (10).
