Re: [Testbed-admins] Booting error in Customizing the Generic Image

[Timothy Ficarra <t.ficarra@yahoo.com>]

I succeeded in creating the customized images. Unfortunately, I have not succeeded in booting those images.

When I get to the boot console:
Entering boot wait mode. Type ^C for interactive mode ...
Part:1
Loading MBR and booting system partition 1

BTX loader 1.00 BTX version is 1.01
Consoles: internal video/keyboard
BIOS drive C: is disk0
BIOS 640kB/2094619kB available memory

FreeBSD/i386 bootstrap loader, Revision 1.1
(root@node.newimage.emulab-ops.emulab.net, Mon Jan 8 12:49:40 MST 2007)
Loading /boot/defaults/loader.conf

At this point the screen flickers, and it does nothing more. I have a very similar problem with FC6. It will call up GRUB but freeze at
Uncompressing Linux... Ok, booting the kernel.

Regards,
T Ficarra

It's up at http://www.emulab.net/downloads/linux_boot.tar.gz.  You can
just extract the linux_mfs.tar.gz tarball into /tftpboot like before
and ignore the rest of the stuff (nothing else has changed).

The mount_bsd_slice script will automatically figure out which Linux
partitions are mapped to which BSD partitions, and mount all of the
UFS partitions in the BSD slice in the correct order.  It should even
work if you have more than our standard 3 BSD partitions (/, /usr, and
/var).

Unfortunately, you'll need to unmount everything manually.  Run
'mount' to see what's mounted underneath the mountpoint you passed to
mount_bsd_slice and unmount each partition manually.

Let me know if you have any problems.
