Philip Charles released the K10 Debian GNU/Hurd CDs. They are a snapshot of the current hurd-i386 packages in Debian's unstable distribution and a small number of modified packages from the unreleased distribution at ftp.gnuab.org. For installation, a customized (Linux-based) boot-floppies (Debian's former installer) is used which will partition the hard disk and then install Debian GNU/Hurd on it. There is a mini-ISO available as well.
Based on the K10 release, Ben Asselstine has released a new version of the GNU/Hurd Live CD as well. It is currently still console-based (X11 support is being worked on), but should give a first impression of a GNU/Hurd system and be a convenient way to check whether the hardware is supported by GNU Mach.
