[oe] [meta-oe][PATCH] plymouth: allow disabling the dracut dep

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

Add a 'initrd' PACKAGECONFIG to disable emission of the plymouth-initrd
package which includes initramfs files for use by dracut. Disabling this will
avoid the runtime dependency on dracut, which is useful if one doesn't need or
want dracut and doesn't want to pull in meta-initramfs.
