# On other systems which supports a boot menu we add
# the linux kernel and initrd with its file names
# like this:
#
# kernel=`echo $i | cut -f1 -d:`
# initrd=`echo $i | cut -f2 -d:`
#
# But on arm systems there can only be one kernel because
# uboot doesn't support a menu. Thus perl-bootloader also
# doesn't support updating the uboot configuration and
# that's the reason why we use the links created by
# mkinitrd to point to the kernel and initrd in order
# to support kernel updates
