Warewulf can be used to boot an selinux-equipped node. This example installs
required packages and configures SELinux policy for the wwclient binary
(which communicates with the Warewulf server and receives runtime overlays).
podman build . --tag rockylinux-selinux:9
Booting a node image with selinux enabled requires (at least up to Warewulf
v4.4.1) setting --root=tmpfs on the relevant node and setting
rootfstype=ramfs as a kernel argument. For more information on these
settings, look at wwinit/init.
