Re: Upgrading kernel on a NSLU2

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.

<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.
