Changing a System's Boot Image
==============================
Making changes to the way a system boots invloves three steps:
1. Back-up existing configuration files.
2. Edit build file.
3. Create new image.
1. Saving the /boot/build/<build.file> and /.boot files
----------------------------------------------------
When making changes to a system's configuration, it is always
recommended that the current configuration be saved. In the case
of changing a system's boot configuration, this involves saving the
/boot/build/<build.file> and the /.boot files.
-> cp /boot/build/<build.file> /boot/build/<build.file>.bak
-> cp /.boot /.altboot
2. Edit build file
---------------
Open the /boot/build/<build.file> file and make the required changes,
making sure to save the file before exitting.
3. Create new image
----------------
In order to create the new boot image, go to the /boot directory and run the
'make' utility on the new <build.file>.
-> make b=<build.file>
As a final step, copy the new image to /.boot.
-> cp /images/<build.file> /.boot
The next time the system is re-booted the new boot image will be used. |
