+Instead of attempting a [[history/port_to_another_microkernel]], or writing an
+own one, an implementation of a Hurd system could use another existing
+operating system/kernel, like [[UNIX]], for example, the Linux kernel. This is
+not a [[microkernel]], but that is not an inherent hindrance; depending on what
+the goals are.
+
+There has been an attempt for building a [[Mach_on_top_of_POSIX]].

+Richard's X-15 Mach re-implementation:
+
+ <braunr> and in case you didn't notice, it's stalled
+ <braunr> actually i don't intend to work on it for the time being
+ <braunr> i'd rather do as neal suggested: take linux, strip it, and give it
+ a mach interface
+ <braunr> (if your goal really is to get something usable for real world
+ tasks)
+ <antrik> braunr: why would you want to strip down Linux? I think one of the
+ major benefits of building a Linux-Frankenmach would be the ability to
+ use standard Linux functionality alongside Hurd...
+ <braunr> we could have a linux x86_64 based mach replacement in "little"
+ time, with a compatible i386 interface for the hurd
+ <braunr> antrik: well, many of the vfs and network subsystems would be hard
+ to use
+ <antrik> BTW, one of the talks at FOSDEM was about the possibility of using
+ different kernels for Genode, and pariticularily focused on the
+ possibilities with using Linux... unfortunately, I wasn't able to follow
+ the whole talk; but they mentioned similar possibilities to what I'm
+ envisioning here :-)
