I am really worried on using apt-get to upgrade the kernel. Can somebody guide me on how to upgrade the kernel. More specifically the following are my concerns. (I am referring to Installing Debian on the Linksys NSLU2 <http://www.cyrius.com/debian/nslu2/install.html> guide)

1. There is an unofficial debian image at http://www.slug-firmware.net/d-dls.php
which has the IXP4xx microcode.
  I remember installing this on my NSLU2.


I installed my NSLU2 exactly the same way in September 2007 (I think). As long as I stick to debian etch in sources.list,

  aptitude upgrade

works just fine.


The microcode is saved somewhere on the hard drive, and when the kernel is upgraded, the slug automatically builds a new flash image including the kernel, drivers and I think the boot system and then writes it to the the internal memory. This takes some time, so it's better to run that in a screen session.

I'd recommend to backup your image though, using

  cat /dev/mtdblock* > image-backup.bin

and copying the result to your computer. If anything goes wrong, you can just write that image back using upslug2 or the Sercom tool.
