Whether to enable the simple preparation of symlinks to the system
generations in /boot.
Whether to create symlinks to the system generations under
<literal>/boot</literal>. When enabled,
<literal>/boot/default/kernel</literal>,
<literal>/boot/default/initrd</literal>, etc., are updated to
point to the current generation's kernel image, initial RAM
disk, and other bootstrap files.
This optional is not necessary with bootloads such as GNU GRUB
for which the menu is updated to point to the latest bootstrap
files. However, it is needed for U-Boot on platforms where the
boot command line is stored in flash memory rather than in a
menu file.
