You can still use the kernel stub to boot directly your OS, but you may need to specify the root fs, if it is BTRFS (not sure about others): $ grep CONFIG_CMDLINE /usr/src/linux/.config # CONFIG_CMDLINE_PARTITION is not set CONFIG_CMDLINE_BOOL=y CONFIG_CMDLINE="root=/dev/sda2 rootfstype=btrfs" # CONFIG_CMDLINE_OVERRIDE is not set Also the fs type should be built directly in the kernel, rather than a module. -- Regards, Mick
