Not true.  We ship units with SW /boot and / all the time, running 
RHEL5.x.  Grub (late model) knows how to handle this, though lilo might 
not.  The issue is, for Redhat folks, you *have* to use their kernels, 
which have special dmraid magic, rather than md raid magic.  The latter 
works ... *much better* than the former, but you have to upgrade (read 
as rip out) nash and several others to get the unit to boot other than 
baseline kernels.
