Making modular my previous changes for armv5tel. I updated the way to use
grub. Its options are no more inside 'boot', but inside 'boot.loader.grub'.
I added a new bootloader configuration for nixos, generationsDir. It creates
/boot/default/{init,initrd,kernel,system} symlinks, and the same for the generations
in /boot/system-$gen/{init,initrd,kernel,system}.
I can program the u-boot loader to load /boot/default files always, and have
a minimal nixos boot loader installer functionality. Additionally, I can refer
to the other system generations easily, with a simple 'ls' in /boot.
