This is correct - we don't recommend any Debian-specific way to build
virt-p2v (except maybe the virt-builder method, but that has some
drawbacks). SUSE contributed their own tool, using "kiwi". A Debian-
based tool would presumably have to use the bootcd method
(
https://packages.debian.org/stable/bootcd), but no one has
contributed that support.
The dependencies.m4 file is shared across all distros (as well as
having per-distro sections) but as long as it doesn't regress on other
distros then it's all fine.

Just adding packages for Fedora/RHEL cannot regress other distros. If
we try to build virt-p2v for some old RHEL, it won't have these
packages, which is not a problem as it will continue to build the old
BIOS-based image.

Looks good, so:
