I am new to both linux and knoppix. I did a knoppix-style harddrive install of knoppix a couple of weeks ago and everything works fine! However I would like to upgrade to a newer version (I am running the 2.4.22-xfs kernel). I have the sources.list as set up from knoppix-installer with the addition of marillat's page for mplayer and codecs, as well as nvidia site for graphics driver. I have tried running
apt-get update and apt-get dist-upgrade, but I still have the 2.4.22-xfs kernel (The 2.4.23-xfs is in the current knoppix version i believe). Moreover, the sources list seems to include the unstable version of Debian, which currently has the 2.6.0 kernel (which would be brilliant, if it works without cinfiguring my hardware manually). Could anyone tell me how to upgrade to Sid (without doing a fresh install), and if so is the hardware configuring plug-and-play like in knoppix? Also, I am wondering why the kernel has the -xfs extension?

I am very greatful for all the help I get!
