You could append +chrony to the $time line in /etc/insserv.conf as a local
fix. You might be able to ship a /etc/insserv.conf.d/chrony that to that
effect but I'm unsure whether that would replace or add to the existing
line. I couldn't find documentation on exactly how the /etc/insserv.conf.d
files work.
