shepherd -> guile 2.2?

[Ricardo Wurmus]

Hi Guix,

I have built shepherd with guile-2.2, but I noticed a couple of
warnings/errors during the build:

Is this bad?  Should I do something to avoid this?
And lastly: should we keep a guile-2.0 variant of the shepherd, or is it
fine to push this tiny change?

This is because the build does not set XDG_CACHE_HOME.  See:

Here you will get more info if you set the
GUILE_WARN_DEPRECATED=detailed variable.

Not a deal-breaker; worth having a look at though.

Something to look into.

Replace with "apply".

I would say don't bother keeping it.

Hi Ricardo,

I’m pretty sure those warnings are due to  IOFBF and friends.  They’ll
haunt us for years to come.  :-)

(But you can happily ignore them.)

No, we can do that in ‘core-updates’ only.

The reason is that we import code in the Shepherd, via the gexps in the
‘start’ and ‘stop’ fields of <shepherd-service>, and those modules are
currently built with ‘default-guile’, which is 2.0 in master and 2.2 in
‘core-updates’.

So yeah, in ‘core-updates’, we can happily move the Shepherd and mcron
to 2.2, but not in ‘master’.
