Add a MIN_CONFIG_TYPE that can be set to 'test' or 'boot'. The default is 'boot' which is what make_min_config has done previously: makes a config file that is the minimum needed to boot the target. But when MIN_CONFIG_TYPE is set to 'test', not only must the target boot, but it must also successfully run the TEST. This allows the creation of a config file that is the minimum to boot and also perform ssh to the target, or anything else a developer wants. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

$config_help{"BUILD_DIR"} = << "EOF"

The directory that contains the Linux source code (full path).

\${THIS_DIR} which is assigned \${PWD} but may be changed later.

POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL'
|

|

Way to reboot the box to the test kernel.
|
|
Only valid options so far are "grub" and "script".
|
|
|
|
If you specify grub, it will assume grub version 1
|
|
and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
|
|
and select that target to reboot to the kernel. If this is not
|
|
your setup, then specify "script" and have a command or script
|
|
specified in REBOOT_SCRIPT to boot to the target.
|
|
|
|
The entry in /boot/grub/menu.lst must be entered in manually.
|
|
The test will not modify that file.
|
|
EOF

$config_help{"GRUB_MENU"} = << "EOF"
|
|
The grub title name for the test kernel to boot
|
|
(Only mandatory if REBOOT_TYPE = grub)
|
|
|
|
Note, ktest.pl will not update the grub menu.lst, you need to
|
|
manually add an option for the test. ktest.pl will search
|
|
the grub menu.lst for this option to find what kernel to
|
|
reboot into.
|
|
|
|
For example, if in the /boot/grub/menu.lst the test kernel title has:

title Test Kernel

kernel vmlinuz-test
