+# Hurd + Guix
+
+* a few people in the room have run the Hurd before, even less on baremetal
machines
+
+## Challenges
+* hurd on bare metal is difficult -> missing drivers
+* hurd supports only small disks (up to 100GB or so)
+* mach provides less then Linux kernel (file system, network etc) -> bootstrap
is hard
+
+## Upstream status
+* 64bit (x86) support WIP
+* support for SMP (multi-threading)
+* port to aarch64 was started
+* Debian is mostly used for developing/integrated
+* activity increased a lot in the last 2 years (1 person -> couple
contributors)
+* patches are pushed to glibc upstream
+
+## Guix on hurd
+* netdde (Linux kernels built for mach) -> Guix integration non-working
+* rumpdisk, disk drivers from NetBSD -> integrated in Guix already
+* rumpnet (for WiFi, network drivers etc.)
+* Guix with Hurd image available https://guix.gnu.org/en/download/latest/
including:
+ * netdde and rumpdisk included
+ * shepherd
+* glibc in core-updates contains many improvements for the Hurd
+ * 2.39 brings even more fixes, but maybe to late for core-updates
+* Bordeaux and Berlin build farms build packages for i586-gnu
+ * only master, core-updates currently disabled
+* `guix system reconfigure` broken on core-updates
+* rust@1.75 is cross-compilable from Linux
+* Mes builds on the hurd, stage0 misses support for mach+hurd
+ * so no bootstrap of Guix yet
+
+## Ideas
+* implement /gnu/store as a hurd translator
+* install Hurd via Guix installer
+* writing Guile bindings for Hurd translator
+* work closer together with Hurd devs
+* mach kernel can be "stretched" over network -> build "clusters"
+
+* how can users/devs start with Hurd
+ * run either via childhurd or Hurd VM
+ * childhurd allows offloading from Guix@Linux
+ * write a simple translator
+* what would help the Hurd ecosystem
+ * fix failing packages
+* empower users (non-admins) -> idea shared by Hurd and Guix
+ * "Linux+systemd+rust" is making things complex (high entry barrier)
