I'm telling you that this constitutes "having trouble". 8)
$root_disk_unit should only be required if you have a discontinuity in
the chain of devices from bios disk 0x80 to your root device.
It would help *immensely* if you were a little forthcoming with eg.
what it is that you have to set $root_disk_unit to. Also, as I've
tried to make clear here, changing the /etc/fstab entry for / is
*WRONG* and if you find yourself having to do this it's because
something is screwed elsewhere.
Again, please *ensure* that your loader is fully up to date. So far
everyone that's reported problems has been using an out-of-date loader.
