* doc/contributing.texi (Building from Git): Mention value /etc to sysconfdir
option.
---
Hi,
From a discussion [1] about a reproducibility issue,
As discussed on IRC, ‘guix pull’ preserves the settings of the host
Guix. So if your initial ‘guix’ has %sysconfdir set to
/usr/local/etc, ‘guix pull’ will preserve that.
It turns out that, as is always the case with GNU Standards compliant
configure script, the default value for --prefix is /usr/local, and
the default for --sysconfdir is $prefix/etc.
Mostly likely, what happened is that at some point you built Guix from
source using the default prefix and sysconfdir, and then you ran ‘guix
pull’ from that Guix.
I discovered that the option ’sysconfdir’ at ./configure time is set by
default to /usr/local/etc conforming the GNU Coding standards. And Guix
expect instead /etc. As 'localstadir', it is unconventional.
The manual does not mention this subtility. This patch adds a tiny sentence
to avoid the trap for the attentive reader.
Thanks,
simon
