Kernel subcommands

Generate Initrd

$> rhctl kernel gi --help
Rebuild Dracut initrd images.

$> # Generate all initrd images of the kernels available on boot dir.
$> rhctl kernel geninitrd --all

$> # Generate all initrd images of the kernels available on boot dir
$> # and set the bzImage, Initrd links to one of the kernel available
$> # if not present or to the next release of the same kernel after the
$> # upgrade.
$> rhctl kernel geninitrd --all --set-links

$> # Generate all initrd images of the kernels available on boot dir
$> # and set the bzImage, Initrd links to one of the kernel available
$> # if not present or to the next release of the same kernel after the
$> # upgrade. In addition, it purges old initrd images and update grub.cfg.
$> rhctl kernel geninitrd --all --set-links --purge --grub

$> # Just show what dracut commands will be executed for every initrd images.
$> rhctl kernel geninitrd --all --dry-run

$> # Generate the initrd image for the kernel 5.10.42
$> rhctl kernel geninitrd --version 5.10.42

$> # Generate the initrd image for the kernel 5.10.42 and kernel type vanilla.
$> rhctl kernel geninitrd --version 5.10.42 --ktype vanilla

$> # Generate the initrd image for the kernel 5.10.42 and kernel type vanilla
$> # and set the links bzImage, Initrd to the selected kernel/initrd.
$> rhctl kernel geninitrd --version 5.10.42 --ktype vanilla
