scyld-* Wrapper Scripts

When creating a new boot image, it's common to create a corresponding boot configuration and assign that configuration to a set of nodes. The scyld-add-boot-config tool wraps scyld-modimg, scyld-mkramfs, and the appropriate scyld-*ctl tools to perform the necessary steps. The tool also optionally displays the required steps so you can learn about the usage of the underlying tools.

When executed with no arguments, the scyld-add-boot-config script asks a series of questions to define the various fields of the boot configuration, image, and attribute group that are being created. Default values are provided where possible.

Important

The default kernel command line sets SELinux on the compute nodes to permissive mode.
