Subject: [bug#63527] [PATCH v5 00/11] Rumpdisk support for the Hurd, really, *really*!
Date: Tue, 23 May 2023 17:47:21 +0200

Hi!

So, with lots of kind help from the folks at #hurd and bug-hurd, and many
thanks to Josselin Poiret for sending their amazing "Add libc specific to Hurd
and update components" patch set (https://issues.guix.gnu.org/63641, note that
these series depend on this!) we now have rumpdisk support for the Hurd.

To actually use it instead of the gnumach builtin IDE driver, use

    (kernel-arguments '("noide"))

To test this, I'm using this patch

./pre-inst-env guix system image -t hurd-raw gnu/system/examples/bare-hurd.tmpl --keep-failed

--serial mon:stdio                                      \
--hda /gnu/store/l35gz57nrkngc923f9zp9awxmq7ha1hc-disk-image

(It also still works without using "noide", we're still using that for
childhurd service where rumpdisk does not really make sense).

Enjoy!
