GNU Hurd 0.7 & GNU Mach 1.6 Released

Written by Michael Larabel in GNU on 31 October 2015 at 02:00 PM EDT. 5 Comments
Stepping ahead of the Linux 4.3 release is a Halloween release of GNU Hurd 0.7, GNU Mach 1.6, and GNU MIG 1.6.

GNU Hurd 0.7 improves the node cache for the EXT2 file-system code (ext2fs), improves the native fakeroot tool, provides a new rpcscan utility, fixes a long-standing synchronization issue with the file-system translators and other components, and the Hurd code has been ported to work with newer GCC versions and libc.

The GNU March 1.6 microkernel also has updates for compiler compatibility, improvements to the lock debugging infrastructure, the kernel now lets non-privileged users write to a small amount of memory, timestamps are now kept relative to boot time, and there are various bug-fixes.

GNU MIG 1.6 is a small update and a new version of glibc 2.19 catering to Hurd was also released today.

More details on today's big GNU Hurd update can be found via While today's announcements are a step forward for Hurd, GNU Hurd's hardware support is still in very poor shape.

Given the lack of modern hardware support for Hurd. the most sane way to try it right now is using Debian GNU/Hurd within a QEMU guest. Back this summer I posted some Debian GNU/Hurd 2015 vs. GNU/Linux benchmarks.
