Mark is correct: swap was never enabled in the first place.  I tested
this by booting an old configuration and entering `cat /proc/swaps`,
which returned an empty table.

Case closed, I guess!

I suspect this never worked, but that before the error was silently
ignored.  In my case, I had:

  (swap-devices '("/dev/disk/by-label/jojen-swap"))

and /dev/disk went away at some point due to another problem.  For a
long time, I simply had no swap.  With the dmd -> shepherd transition,
it started causing a fatal error during boot, leading to a kernel panic.
Unfortunately, the error message scrolled off the screen very quickly,
obscured by a useless kernel backtrace.

Apologies, that’s the aftermath of the dmd → shepherd transition.

The solution was to run /run/booted-system/profile/sbin/reboot, which
would have been able to the running dmd (whereas after reconfiguration,
‘reboot’ was the new Shepherd client, which cannot talk to the old dmd.)

I don’t see anything immediately obvious.  I tried your config in ‘guix
system vm’ and it works fine, so perhaps the problem has to do with
device mapping or similar.

How did you set up the encrypted root partition?  Did you use ‘guix
system reconfigure --no-grub’ and a hand-made grub.cfg?

Thanks,

I’m not sure I follow.  Does upstream khal explicitly intend to install
its own bin/vdirsyncer?

Hi again,

I got rid of the kernel panic by removing the following from the config
and reconfiguring (as suggested by Mark Weaver):

> (swap-devices '("/swapfile"))

It would be nice to be able to enable swap again though. On my system it
needs to be done with a swap file.

bug#22548: Kernel panic after system reconfiguration

[Albin]

Hi,

With no other changes I just ran guix pull and guix system reconfigure
on my MacBook2,1 which created an unbootable system.

After having completed the reconfiguration I tried to halt and reboot
the system but got this error message each time :

> error: connect: /var/run/shepherd/socket: file or directory does not exist

I did a hard shutdown and rebooted.

Here is a picture of the kernel panic screen:
https://lut.im/h3kmF9hN8D/pnbWoVVQWj7QYPkr.jpg

This is my system configuration:
http://paste.lisp.org/display/306452

The OS was quite bootable after my last reconfiguration on January 26.

bug#22546: Download-Page is "hiding" what the options actually are

[Robin Vobruba]

Being new to Guix, i went to the Download page:
https://www.gnu.org/software/guix/download/

immediately saw the 3 big options
read their title/names
was confused what the difference might be between "GuixSD" and "Guix Binary"
could not find anything inside these 3 option's boxes that would help me
read the text below them
read the text above them
finally understood that the first option is the OS, and the second is only
the packag-manager

i think that the first option should have a title saying "Operating System
install medium" or the like, and the second "Package-Manager for arbitrary
Linux".
nobody is going to read a small, regular text formatted, two lines long
paragraph on a download page, but this is very crucial information for
everyone that gets there.


... sounds like a very good project! :-)

bug#22543: 404 in Manualpage

[Nils Gillmann]

The manual page
https://www.gnu.org/software/guix/manual/html_node/Requirements.html#Requirements

contains a link to

https://www.gnu.org/software/guix/manual/gnutls-guile/Guile-Preparations.html#Guile-Preparations

which give a 404. I am not familiar with what's supposed to be there, a
quick search for "gnutls-guile/Guile-Preparations.html" in duckduckgo gives me
http://www.gnutls.org/manual/gnutls-guile/Guile-Preparations.html as one
of 2 results.

Should I fix the link to this one and send in a patch?

Here’s a first stab at this.

As an example, I modified ‘python-matplotlib’ to use that feature, so we
can test that ‘python2-scipy’ is using the right ‘python2-matplotlib’:

--8<---cut here---start->8---
$ ./pre-inst-env guix build python2-matplotlib -d 2>/dev/null
/gnu/store/07zr2pqg61b742czb2aqyisml2i90r4a-python2-matplotlib-1.4.3.drv
$ ./pre-inst-env guix build python2-scipy -d 2>/dev/null
/gnu/store/8yhxdbyjvx2xwynpqqcrj9ilksd2pb01-python2-scipy-0.16.0.drv
$ guix gc --references 
/gnu/store/8yhxdbyjvx2xwynpqqcrj9ilksd2pb01-python2-scipy-0.16.0.drv | grep 
python2-matplotlib
/gnu/store/07zr2pqg61b742czb2aqyisml2i90r4a-python2-matplotlib-1.4.3.drv
--8<---cut here---end--->8---

This will trigger rebuilds (but with an identical result) because in
manually-written variants we would use “python2-foo” as the label of
inputs, whereas the automatic transformations keeps the original
“python-foo” label.

What do people think?

I can apply this patch of the approach sounds good to you.  I think we
should probably do one commit per rewrite for clarity.

We should probably start with the lowest level, like python2-pycairo and
python2-pygobject and even python itself, because if we fix them then
some of the higher-level stuff won’t even need their own
‘python2-variant’ property.  For instance, if python, pycairo, and
pygobject have their ‘python2-variant’ set, then we no longer need this:

--8<---cut here---start->8---
(define-public python2-matplotlib
  (let ((matplotlib (package-with-python2 %python-matplotlib)))
(package (inherit matplotlib)
  ;; Make sure to use special packages for Python 2 instead
  ;; of those automatically rewritten by package-with-python2.
  (propagated-inputs
   `(("python2-pycairo" ,python2-pycairo)
 ("python2-pygobject-2" ,python2-pygobject-2)
 ("python2-tkinter" ,python-2 "tk")
 ,@(fold alist-delete (package-propagated-inputs matplotlib)
 '("python-pycairo" "python-pygobject" "python-tkinter")))
--8<---cut here---end--->8---

… and as a consequence, we don’t need a ‘python2-variant’ in
‘python-matplotlib’.

Does that make sense?  Any takers?  (This can be done incrementally.)

Thanks,
Ludo’.
