[bug#68258,0/7] Upgrading Shepherd and moving the Hurd to 0.10.x

Hello Guix!

With the upcoming Shepherd 0.10.3, which I plan to publish in the
coming days, I’d like to make these changes: switching the Hurd to
0.10.x (instead of 0.8.x!) since it’s now functional, which in turn
allows us to use the 0.10.x interfaces (GOOPS-less; this is a step
before the Shepherd 1.0, which will not support the GOOPS interface
at all¹).

Thoughts?

Yay!  I had trouble building (running the test suite of?) fibers before
on the Hurd, IIRC.

I haven't re-checked this, so we might have to check this or disable
(some) tests to allow native builds.  Really just wildly guessing here.

Hmm, I've built a bare-hurd.tmpl but ssh doesn't start for me (see log).

A line similar to

--8<---------------cut here---------------start------------->8---
/gnu/store/3lqwp154zlj79ndm92ay9g0hwvjsf3m9-sshd_config line 13: Unsupported option UsePAM
--8<---------------cut here---------------end--------------->8---

that used to appear second-last is now missing (see log).

(I've tried reverting 1/7 but that doesn't work)

So, I've tried without CONSOLE=COM0 using --display curses and the
problem is that (ipv6) networking didn't, and won't start anymore:

--8<---------------cut here---------------start------------->8---
root@guixydevel ~# herd start networking
starting '/gnu/store/9mxaxp5nj70d5wkn8d32bxhybfvglvi3-hurd-v0.9.git20230216/hurd /pfinet "--ipv6" "/servers/socket/26" "--interface" "/dev/eth0" "--address" "10. 0.2.15" "--netmask" "255.255.255.0" "--gateway" "10.0.2.2"'
herd: error: exception caught while executing 'start' on service 'networking':

--8<---------------cut here---------------end--------------->8---

That doesn't tell us much, but running

--8<---------------cut here---------------start------------->8---
settrans --active --create --keep-active /servers/socket/2 /gnu/store/9mxaxp5nj70d5wkn8d32bxhybfvglvi3-hurd-v0.9.git20230216/hurd/pfinet --ipv6 /servers/socket/26 --interface /dev/eth0 --address 10.0.2.15 --netmask 255.255.255.0 --gateway 10.0.2.2
--8<---------------cut here---------------end--------------->8---

Gives

    .../hurd/pfinet: /servers/socket/26: Device or resource busy

Any ideas how this may have happenened?

FWIW, reverting to shepherd-0.8

cd1100482d Revert "system: hurd: Use the Shepherd 0.10.x."
d82e9a0494 Revert "services: shepherd: Use the 0.10.x GOOPS-less interface."

"fixes" starting of networking.  :-(

Log attached.

There were a couple of issues on the way.  Most likely you hit
<https://issues.guix.gnu.org/64653> (now fixed), which was marking
‘networking’ as failing to start even though pfinet had been correctly
started.  Consequently, re-running ‘herd start networking’ would fail as
above because the translator was already running.

So if you rebase above 4e431fda5f2ec76b6d6a271be7c30b1324431329, it
should be fine!

Yeah, so far I was testing the Shepherd’s test suites with:

  guix build -s i586-gnu -f guix.scm --without-tests=guile-fibers

I’ve already identified a bug in the libevent backend of Fibers; I’ll
take a look at the test suite.

Thanks for testing!

Yes, it now works for me.  I'm not sure how I missed this, sorry :)

Finally shepherd 0.10 on the Hurd, well done!

Pushed as 3eac1c82f7f1547aa6819db867b071a4ee7de8e3!

Commit 766ac72dba36657ce217d055d7672cbf01bd32ce also fixes a bug in the
libevent backend of Fibers (fix is now upstream:
<https://github.com/wingo/fibers/pull/102>).
