Where should It come from? I don't have any rootfsflags in my grub2.

It gets added to the kernel command line by the pre_checkin.sh script.


Now I see, I've grepped rootfsflags instead of rootflags.

Meh, I always get those wrong :).


Unfortunately, my board has only 256MB of RAM, so last time I need to
use rootfstype=ramfs to cope with huge initrd and it worked somehow.

Phew. So with EFI enabled, we need to have all of grub2 inside the
initrd (thanks to kiwi). Since your initrd with grub2 is almost 50mb
packed, I'd say we really just exceed the 256MB in your case.

Hm, two weeks ago it was 33MB. Now it is clear, except why there is no
output on console with ramfs.

#define USE_EFI adds grub2 to the initrd, bloating it up by a few mb...
