Re: [Lug-bg] bootcd problem

["Vladimir Vitkov" <vvitkov@xxxxxxxxx>]

Тъп въпрос но какво да се прави ... В кернела имаш ли поддръжка на
initramfs
ramdisk
initrd
cramfs

По принцип грешката която ти хвърля навява на мисълта че не може да си
намери файловата система.

Може също така да пробваш с
  append="root=/dev/rd/0"
