The MIN_CONFIG is a single config that is considered to have all the configs that are required to boot the box. ADD_CONFIG is a list of configs that we add that may contain configs known to be broken (set off) or just configs that we want every box to have and this can include shared configs. If a config has no MIN_CONFIG defined, but has multiple files defined for the ADD_CONFIG, the test will die, because the MIN_CONFIG will default to ADD_CONFIG. The problem is the code to open MIN_CONFIG expects a string of one file, not multiple, and the open will fail. Since the real minconfig that is used is a concatination of MIN_CONFIG and ADD_CONFIG files, we change the code to open that instead of whatever MIN_CONFIG defaults to.

$config_help{"SSH_USER"} = << "EOF"
|

The box is expected to have ssh on normal bootup, provide the user

The directory that the objects will be built (full path).

A script or command to reboot the box.

Here is a digital loggers power switch example
|
|
POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL'
|
|
|

Here is an example to reboot a virtual box on the current host
|

with the name "Guest".
|
|
POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
|
|
EOF

$config_help{"CONSOLE"} = << "EOF"
|

The script or command that reads the console
|

If you use ttywatch server, something like the following would work.
|

CONSOLE = nc -d localhost 3001
|
|

|
from other linux builds on the system.

EOF

$config_help{"REBOOT_TYPE"} = << "EOF"
|
|
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
|
|
GRUB_MENU = Test Kernel
|
|
EOF
|
|
;

A script to reboot the target into the test kernel
