Great, I like it, and the meaning is the same.

In the Alpha criteria we already require that "all" provided boot methods work, which means netinst, DVD and Live [1]. I don't think PXE/kernel boot should be different in this case, the images are provided in the compose alongside netinst, DVD and Live. This criterion just states that we consider vmlinuz+initrd as part of this "all provided boot methods" as well (which is a correct thing in my view).

We could even just easily append it to that criterion [1] itself. But since there are more options in PXE boot (installer not being part of initrd and other complications), we would have to assume a lot of things silently, or mention it explicitly anyways, so a separate criterion seems better and more readable.

[1] "The installer must boot (if appropriate) and run on all primary architectures, with all system firmware types that are common on those architectures, from default live image, DVD, and boot.iso install media"
