Well, it will be hard to match all of the criteria. You could always look at
Linuxiso.org or at Linux.org's
distribution page. I'm going to recommend
Knoppix installed on a harddrive with knx-hdinstall I believe.. You might want to try
Ark Linux. The thing is you are rarely going to find an installer as clean as Mandrake. Ark Linux's installer is very easy to use but I'm not sure if you can use Reiser in it though. And lastly you can check the
reviews section of the page for other distributions.
