What I'm proposing is a bit different. The idea is to have Debian running
inside a container on CentOS *without* Debian having its own boot process.
Basically, CentOS would use its own systemd, and Debian would be running
inside a container as a glorified chroot without its own systemd copy, via
Docker or rkt or systemd-nspawn (which fits with the "glorified chroot"
idea) or whatever else.
Yes, it sounds stupid, and it probably is, but hey, it would work. 😉
