Hi Simon,

Simon Josefsson <simon <at> josefsson.org> skribis:

> Thank you! Does this make shepherd Debian packages useless, or can we suggest people to ignore the warning? Any simple way to patch it out from within shepherd? The Debian freeze is in two weeks and it would be nice to give a good first impression to people try it shepherd from Debian… i could try to get guile patched, but it is getting late.

A simple way would be to patch out the ‘environ’ warning in Guile: it
didn’t exist before 3.0.10, it’s bogus (it fires even when you’re not
mutating the environment and even with just a single user thread, as is
the case here), and the comment itself doesn’t change program behavior.

If that’s not adequate, we could try and come up with a quick hack for
shepherd to avoid the ‘environ’ call at the top-level (though that’s
probably not something I would consider for inclusion in the Shepherd
proper.)

WDYT?

Ludo’.
