Right, it’s a warning (not an error), so you can proceed.  To address
it, see
<https://www.gnu.org/software/guix/manual/html_node/Application-Setup.html#Locales>.

It depends.  It may be that some derivations would be built, and others
would be downloaded.  That can happen for instance if the build farm
hasn’t yet built the Emacs you’re asking for.

We arrange for the build farm to provide binaries as fast as possible,
but sometimes it’s just lagging behind and users have to build from
source.

HTH!
