The description above implies that you will only uninstall update-rc.d
if systemd is present, but that doesn't seem to be what the patch does.

Also, if the rootfs is read-only then you might as well go ahead and
uninstall it irrespective of systemd because it isn't going to work.  If
systemd will fail catastrophically in this situation then I guess it
should be an error to have both systemd and sysv scripts in a read-only
filesystem.
