Subject: [PATCH] Look at DEBBUGS_DATA for Debbugs data.

From: Felix Lechner <[email-masked]>
Date: Mon, 13 May 2024 12:54:44 -0700

Maintaining symbolic links to Debbugs data is not reasonable burden
for co-existing installations of various versions of Debbugs and Mumi.

This change further allows the location to be configured in an
operating-system declaration that syncronizes the data from
debbugs.gnu.org via a Shepherd timer.  A patch with a 'configuration'
record is available but has not been submitted.
