GNU Hurd 0.6 released
It has been roughly a year and a half since the last release of the GNU Hurd operating
system, so it may be of interest to some readers that GNU Hurd 0.6 has been
released along with
GNU Mach 1.5 (the microkernel that Hurd
runs on) and GNU MIG 1.5 (the Mach Interface Generator, which
generates code to handle remote procedure calls). New features include
procfs and random translators; cleanups and stylistic fixes, some of which
came from static analysis; message dispatching improvements; integer
hashing performance improvements; a split of the init server into a
startup server and an init program based on System V init; and more. "GNU Hurd runs on 32-bit x86 machines. A version running on 64-bit x86
(x86_64) machines is in progress. Volunteers interested in ports to
other architectures are sought; please contact us (see below) if you'd
like to help.

To compile the Hurd, you need a toolchain configured to target i?86-gnu;
you cannot use a toolchain targeting GNU/Linux. Also note that you
cannot run the Hurd "in isolation": you'll need to add further components
such as the GNU Mach microkernel and the GNU C Library (glibc), to turn
it into a runnable system."
