Comment # 5 on bug 906990 from Jiri Srain

AFAIK Linuxrc does not load other boot loader - it just mounts the target
system and chroots into it. This is something that I don't believe you can do
from GRUB itself.

Even adding such a section to boot menu may not be possible - if nothing else,
the target root partition is different in every case and the other GRUB can be
also installed in so many locations. Not to mention BIOS disk order, which
could possibly prevent booting as well.


If you have any more detailed idea how to implement such feature, I'm open to
give it a try - but I'm rather pessimistic about it. The only thing that could
possibly be done is a shortcut to Linuxrc's selection of root partition to
boot.
