OK. That fits with Bill's idea - if you build without initrd then you would
_have_ to have the root filesystem compiled into the kernel. I could see
that's what was happening (though it really strikes me as a pretty weak
algorithm - there's no point in checking ext3 and surely FAT could be
checked last), but wasn't sure of the correct solution. Once I get a kernel
that works, I always tweak it anyway, so I'll just compile in reiser next
time.
Thanks, both of you
