Sometimes it is necessary to modify the kernel command-line of the image, this adds support for a [customizations.kernel] section to the blueprint: [customizations.kernel] append = "nosmt=force" This will be appended to the kickstart's bootloader --append argument. Includes tests for modifying the bootloader line, the kickstart template, and examining the final-kickstart.ks created for a compose. (cherry picked from commit59464286f9) (cherry picked from commitc5f4dfe113)
