#  Basically we have an OLD (old 7 years ago, as of 2025-10) set of content
# and a new set of content. We want to serve the new content, and if nothing
# exists there then instead serve the old content.

#  The simple way is to:
# 1. rsync old to docs.fedoraproject.org
# 2. rsync new to docs.fedoraproject.org
# 3. rsync docs.fedoraproject.org to docs-combined

# BUT see https://forge.fedoraproject.org/infra/tickets/12848

# -a is the std. copy everything "archive" mode.
# -H means try to copy hardlinks as hardlinks
# --no-times --checksum means that if the file changes mtime we still keep
#                                  the old file (and thus. the old hardlink).
