In theory, any distribution may be used on the host for building
images containing any other distribution, as long as the necessary
tools are available. Specifically, any distribution that packages
-`debootstrap` may be used to build *Debian* or *Ubuntu* images. Any
-distribution that packages `dnf` may be used to build *Fedora Linux*,
-*Mageia* or *OpenMandriva* images. Any distro that packages `pacman` may be used to
-build *Arch Linux* images. Any distribution that packages `zypper` may
-be used to build *openSUSE* images. Any distribution that packages
-`yum` (or the newer replacement `dnf`) may be used to build *CentOS*, *Rocky Linux*,
-or *Alma Linux* images. Any distribution that packages `emerge` may be used to build
-*Gentoo* images.
