The GNU Shepherd 0.9.0rc1 available for testing!

Hello Guix!

A release candidate of the Shepherd 0.9.0 is available for testing!

  https://alpha.gnu.org/gnu/shepherd/shepherd-0.9.0rc1.tar.gz
  https://alpha.gnu.org/gnu/shepherd/shepherd-0.9.0rc1.tar.gz.sig

  SHA256: 6b7cdbb8d2509fca0c4d08b855031ea72c887a65828ae6493c2e5a25130c3c37

You can test it on Guix System with:

  guix time-machine --branch=wip-shepherd-upgrade -- \
    system reconfigure …

and on Guix Home:

  guix time-machine --branch=wip-shepherd-upgrade -- \
    home reconfigure …

Bug reports are most welcome.

The branch changes the ‘ssh-daemon’ service to an inetd-style service:

  https://git.savannah.gnu.org/cgit/guix.git/log?h=wip-shepherd-upgrade

You’re welcome to propose patches to change other services to systemd or
inetd style.

The ‘make-forkexec-constructor/container’ procedure that we have doesn’t
compose well (we’d have to make
‘make-inetd-forkexec-constructor/container’, etc.).  But I think we
could achieve the same thing differently, with wrappers, so that we can
have inetd and systemd services running in containers too.  Future work…

There’s also more work we can do in future Shepherd versions, such as
adding ‘herd journal SERVICE’, moving state out of <service>, adding a
REPL :-), etc., but what we have today is a reasonable milestone IMO.

Besides, a new POT file should be available soon if you’d like to help
translate the new release in your language:

Just to let you know, I've been running on this for a couple days
without any noticing any issue yet.  My boot time has been reduced from
5 to 3 minutes, yay!

Thank you :-)

On my 2010 Macbook Pro (with hard disk, not using SSD), boot time to
GDM got a few seconds slower/faster from 3:08--3:22 minutes to
3:19--3:20 minutes.  (Faster old boot times are a few days old; seems
to vary with temperature or phase of the moon or something.  So it is
maybe not slower at all or maybe even 2 seconds faster.)

I’m using none of the new Shepherd features; no sshd and no childhurds
nor secrets service, just desktop services and GNOME.

But still the new Shepherd is the right thing to do, I think.

Regards,
Florian

OK.  I don’t expect faster boot times on ‘%desktop-services’ because
those are unchanged: either they’re started “greedily” early on (like
elogind, network-manager, etc.), or they’re started lazily by
dbus-daemon.

There’s little room for boot time improvements here, AFAICS, but I’d
love to be proved wrong.

Thanks for testing and reporting back!

Yay, thanks for testing!

I too have been running it for several days, stress-testing it a bit,
and everything’s fine.  :-)

Unless a fly falls in the ointment, I’ll go ahead and release 0.9.0
tomorrow, followed by a merge of the ‘wip-shepherd-upgrade’ branch in
Guix ‘master’.

Thanks,
Ludo’.

Sounds like a fine plan!  Thank you for improving Shepherd!
