update-petitboot.sh

The update-petitboot.sh scripts generates a petitboot.conf file from the files in the /boot directory.

Usage

Install the update-petitboot.sh script to your system (e.g. to /boot/update-petitboot.sh) and then run it after every kernel update to regenerate the menu entries.

Configuration

The update-petitboot.sh script can be configured using a /boot/update-petitboot.conf file. This file will be sourced by the script, so it has to conform to POSIX shell syntax.

In it, you can set these variables:

os_name (default: Linux)

The prefix for all menu entries.

append (default: none)

Kernel cmdline arguments (default: none).

consoles (default: tty)

The consoles the system has to boot.

On OpenPOWER systems this is usually the serial console (hvc0) and the framebuffer (tty).

If you prefer a "nicer" label than the device name you can use the [label=]dev syntax, e.g. VGA=tty or serial=hvc0.
