Therefore, there is no reason, in principle, why you could not build a CentOS userland on top of the Windows Subsystem for Linux. It would be about as difficult as live-migrating a working Ubuntu box to CentOS, replacing binaries one by one until you’re suddenly running a CentOS userland on top of the kernel Ubuntu shipped. Difficult, but do-able. Get to work, Jerry. :)
