Stop Typing in the Full Path during Imaging and Modifying Linux.2

Novell Cool Solutions: Tip
By Sibrand van Minnen

Digg This - Slashdot This Posted: 20 Jul 2005

With Henny van de Ben I was inspired by the modifications from Jan Visser and Box Lawrence. We modified Linux.2 so that it gets a menu file from the TFTP dir on the ZENworks imaging server. The menufile is easy to modify -- it's plain text.

Example

Modification to Linux.2 /bin/prompt.s:
#!/bin/ash
. /bin/config.s manual
mountFloppyifLS120
if [ $? != 0 ]; then echo "Failed to mount floppy drive. If there is a floppy in the drive, remove it before running img"; fi

export MANUALREBOOT=YES
export SHELLACTIVE=YES
## adition
. /bin/getmenu.s
## end adition
ash -rcfile /bin/bashrc

Addition to Linux2 - place this script in a file called getmenu.s
#!/bin/bash
tftp -c get $PROXYADDR:menu.txt /bin/menu
chmod 777 /bin/menu
menu

and make this script executable with chmod 777 getmenu.

Place the following text in the [zenserver]sys\tftp\menu.txt
#!/bin/bash

#       All the menu commands are in the standard kernel which
#       comes with Zenworks.

In the first 30 or so lines you can edit your image menus.

• This is the stuff I like!! Good work.
• If you are using the kernel 2.6.11 version from http://forge.novell.com/modules/xfmod/project/?zfdimgdrv You will need to modify the tftp command, as it does NOT work as described above. (It works with zen 6.5 and 6.5 sp1b). Use this command instead: tftp $PROXYADDR < /bin/getmenu2.s and create a getmenu2.s file that has the following commands: get menu.txt /bin/menu q -mhynek in Madison, WI
