This is a new Focal based host, which we want for it's more recent
rsync which hopefully causes less issues resyncing things to AFS
volumes.
See 4918594aa472010a8a112f5f4ed0a471a3351a91 for discussion of the
original issues; we have found that without "-t" all new data seems to
be copied continuously. Empirical testing shows later rsync doesn't
have this issue.
