# dovecot.socket during prerm. However, if we are upgrading from older
# versions, an incoming IMAP connection between old prerm and upgrade end
# might re-activate dovecot.service with an inconsistent on-disk layout. We
# do a best-effort attempt to avoid this by stopping dovecot.socket and
# dovecot.service here. See #814999 for more details.
