Plain text would be wonderful. In emacs I see some XML header
information and a lot of binary ghibberish...

Thank you very much!

Plain text it is.  Sorry about that.  I am just going to cut/paste, so I
apologize if it is not very readable.

Ghosting Red Hat Linux with grub and ext3 partitions


This white paper describes how to ghost Linux partitions, especially
those with ext3 partitions.  Since Red Hat Linux 7.2, the default
partition type has been ext3, which is a journalling file system.  Ghost
does not recognize the partition as an ext3 partition, and thus removes
the journal inode.  In order to get Linux to boot after having ghosted
it, you must recreate the joural filesystem.  This has been verified
with Ghost 2001 and Red Hat Linux 8.0.


I.   This assumes that you already know how to use ghost and and that
you have some Linux experience.  If you are ghosting a dual-boot machine
(booting to Linux and Windows or another operating system), and the
other operating system won=E2=80=99t boot, you may need to repair the MBR f=
or
the other operating system.  Once you can boot successfully, run the
steps below to reinstall grub.  Before you begin, you should write down
the names of the Linux partitions on the original disk.  `fdisk  =E2=80=93l=
` or
`df` inside of Linux should show you the partitions.  Write down the
/dev/???? names and their corresponding mount points.
E.g.,
/dev/hda2	/boot
/dev/hda5	/
/dev/hda6	/usr


II.   After ghost has completed, you should try to reboot to see if, by
chance, it worked.  Most likely you will get a GRUB screen with a
blinking cursor.  First you need to get a Red Hat Linux CD (disc 1), and
boot into rescue mode:

  a. Boot from the CD
  b .Type  `linux rescue`  at the boot: prompt.
  c.If it asks about verifying your disc, TAB to Skip and hit Enter.=20
Ans wer the questions about your language and keyboard, and Skip the
question about mounting your partitions.
  d. Find out which partitions are Linux native (0x83) if you haven=E2=80=
=99t
done so already.  Write these down for the next step
      i. fdisk =E2=80=93l    (or `fdisk  =E2=80=93l  /dev/hda`, `fdisk  =E2=
=80=93l  /dev/hdb`,
`fdisk  -l  /dev/sda`, etc.).  Write down the Linux partitions (e.g.,
/dev/hda2, /dev/hda5, etc.).


III.  Now you need to remove the information about the journalling
inode, and rejournal the partition.  This will not cause loss of data.

  a.tune2fs  =E2=80=93O  ^has_journal  /dev/hda2   (capital o)
  b.Repeat for each Linux partition.
  c.tune2fs =E2=80=93j /dev/hda2
  d.Repeat for each Linux partition


IV.  Mount the / and /boot (if you have one) partitions on /mnt/sysimage
and /mnt/sysimage/boot respectively.  If you are not sure which is the /
or /boot partition, try mounting each of the Linux partitions, and see
if it contains boot/, bin/, sbin/, root/, etc. directories.  Once you
mount /, check the boot/ directory to see if it contains kernel-* and
vmlinuz-* files.  If it contains no files, /boot is on a separate
partition, and you will need to mount it.

  a. mkdir /mnt/sysimage
  b. mount  /dev/hda5  /mnt/sysimage  (where hda5 is your actual /
partition)
  c. mount  /dev/hda2  /mnt/sysimage  (where hda2 is your actual /boot
partition.  Only mount it if /boot is on a separate partition.)
  d. chroot /mnt/sysimage
  e. grub-install  /dev/hda   (where /dev/hda is the disk that boots
first.  This will write grub to the MBR of the disk.  If your Linux
partitions are similar to /dev/hda5 or /dev/hdb2, you should use
/dev/hda.  If your Linux partitions are /dev/sda5 or /dev/sdb2 (SCSI
disks), you should use /dev/sda.)
  f. Type `exit` to exit the chrooted environment.


V.   Type `exit` to exit rescue mode, and make sure that you remove the
CD so that it doesn=E2=80=99t boot from CD again.
VI.Grub should now work, and you should be able to boot other OSes as
well.

Let me know if that doesn't work better.
