[Devil-Linux-discuss] install-on-usb grub not installed in mbr

[Gerhard O. <ger...@gm...>]

Two problems:
  The install-on-usb script seems to install grub in the first
partition on hd0 (always first IDE?) instead of the selected device.
(It may not be possible boot from something else than  hd0, but that
is adifferent issue...)
  The grub "root" directory where /boot/grub is located is set to
(hd0,0) instead of the actual location of grub (this was the problem
for me since my first partition is swap). Unless you have put the iso
and boot on the first partition on the device, grub cannot find the
grub directory.

A few minor changes as well:
  Default handling a little more reasonable
  Merged handling of serial/normal grub console

Not done:
  There should be separate configuration for where to put grub mbr,
since it may not be on the same disk as the iso, possibly not even on
the mbr. (Since DL is probably not a multipurpose computer, this is
not a real life issue, included here only to let someone else
investigate this).

Patch and diff included.

If you have this problem (or the DL team wants to minimze patches),
the only thing you have to change is (normally) the following:
  root_drive=3D"${install_drive%%)},0)"
    to
  root_drive=3D"${install_drive%%)},$2)"
Disclaimer: I have not tested this separatly
