+ Automatically create extlinux-style boot menu for u-boot. Boot menu
+ entries are automatically created for every kernel package when they are
+ installed.
+ .
+ When /boot is on a separate partition, the package flash-kernel may help
+ ensure that device-tree (dtb) files are made available to u-boot.
