Upgrading to Debian 6.0 (squeeze) on ARM

Debian 6.0 (squeeze) has been released. Here are some notes if you're running Debian on an ARM-based NAS device or plug computer and are planning to upgrade.

First of all, make sure to read the release notes for Debian 6.0 on ARM. This document contains a lot of information on performing a successful upgrade.

Second, during the kernel upgrade, you'll get the following message about the boot loader configuration:

The boot loader configuration for this system was not recognized. These
settings in the configuration may need to be updated:

 * The root device ID passed as a kernel parameter;
 * The boot device ID used to install and update the boot loader.

On ARM-based NAS devices and plug computers, you can simply ignore this warning. We put the root device into the ramdisk so it will be updated automatically.

Finally, after doing the upgrade and before rebooting your system, make sure to run flash-kernel to activate the new kernel.
