This setting is only meaningful if the INITRAMFS_SOURCE is
contains a directory. Setting this user ID (UID) to something
other than "0" will cause all files owned by that UID to be
owned by user root in the initial ramdisk image.
If INITRAMFS_SOURCE points to a directory, files owned by this UID
(-1 = current user) will be owned by root in the resulting image.
If you are not sure, leave it set to "0".
