-# Usage:
-#
-#       qemu-4-build-vm.sh OS [--enable-debug][--dkms][--patch-level NUM]
-#               [--poweroff][--release][--repo][--tarball]
-#
-# OS:           OS name like 'fedora41'
-# --enable-debug:  Build RPMs with '--enable-debug' (for testing)
-# --dkms:       Build DKMS RPMs as well
-# --patch-level NUM:    Use a custom patch level number for packages.
-# --poweroff:   Power-off the VM after building
-# --release     Build zfs-release*.rpm as well
-# --repo        After building everything, copy RPMs into /tmp/repo
-#               in the ZFS RPM repository file structure.  Also
-#               copy tarballs if they were built.
-# --tarball:    Also build a tarball of ZFS source
