As Slackware Linux is approaching a new release (they posted RCpi over the weekend), I have been trying out the Release Candidates. The basic philosophy of Slackware is still the same as it has always been - it is a "hard core" Linux distribution, and those who install it are expected to have at least a reasonable working knowledge of Linux configuration and management - not unlike Debian, but somewhere more extreme in this regard. As with Debian, there are some derivates of Slackware which add more polish to the installer, focus on a specific desktop, add a variety of popular packages, and present themselves as a more "user-friendly" distribution.
The first of those to make a new release is Zenwalk Linux, which announced their 7.0 distribution last Friday. The ISO image is just under 600MB, and is available only for 32-bit Intel (and compatible) architecture. Besides the obvious route of burning the ISO image to a CD, I found a very helpful Zenwalk Wiki article describing how to install from a USB stick.
