Is installing `glibc-locales` necessary on GuixSD?

Is installing `glibc-locales` necessary on GuixSD?

[Ada Stevenson]

Hi Guix!

Congratulations to everyone who worked on the core-updates merge!

A lot of things have changed though, and I was curious about this new 
message I've been getting whenever I invoke `guix`.

I've looked at the section in the manual, and it essentially reiterates 
the message here. For me, this is strange. The benefit of using GuixSD 
is that stuff like this is handled for me - things like search paths and 
the like that need to be taken care of separately on a foreign 
distribution are pre-configured here.

I feel like this new locale change should be one of these things that is 
handled by GuixSD, somehow incorporated into `%base-packages` and the 
environment variables set in the default `.profile` script like the 
other Guix specific env-vars.

What do you all think?

Warmly,
Ada

Hi Guix...

This is embarrassing. I sent this email before I actually reconfigured 
my system, and it seems like the message has gone away and the locales 
are working....... oops!

Please disregard this message!

I missed this message before.  Indeed, once you’ve reconfigured,
/run/current-system/locale is, by default, populated with locale data
for both the old and the new version of glibc.  Thus, both “old”
binaries (linked against glibc 2.35) and new ones (linked against 2.39)
find compatible locale data.

See
<https://guix.gnu.org/manual/devel/en/html_node/Locales.html#Locale-Data-Compatibility-Considerations>.

Cheers,
Ludo’.
