Thank you for the clarification. Indeed, with Efraim's latest patch,
packages seem to be referring to the replacement for glibc-final.

So, do we think this patch is ready to apply? AFAIK, nobody has yet
tried upgrading a GuixSD system with this patch. I won't have access to
my bare-metal GuixSD system for the next few days.

Thank you for your advice and guidance, and to Efraim for taking the
lead on fixing this bug!
