initrd-bootchain: Initial feature

features.in/initrd-bootchain/README

+Осуществляется сборка initrd.img при помощи make-initrd с включенными фичами
+bootchain. Это альтернатива фичи initrd-propagator. Используется тот же список
+модулей ядра, что и при сборке с propagator, но в отличие от последнего модули
+добавляются в initrd.img самим make-initrd.
+Документацию по использованию bootchain следует смотреть в пакетах
+make-initrd-bootchain-*:
+/usr/share/make-initrd/features/bootchain-*/README.md
