This works in >= 220-1 via the systemd-sysv-install wrapper, but not
before. WDYT about the attached patch? I tested that in a Jessie
container. This is more relaxed than the SLINK/SSLINK= further down as
it does not rely on `runlevel`.
Thanks,
Martin

Subject: [PATCH] invoke-rc.d: Add SysV fallback for "systemctl is-enabled" for
systemd < 220
Commit 6dd9d53f4 switched to "systemctl is-enabled" to determine if a service
is enabled. This also has worked for SysV init scripts since systemd 220-1 (via
the systemd-sysv-install wrapper), but does not yet work under Jessie's systemd
215.
Add a fallback to checking runlevel symlinks (for any runlevel) to fix upgrades
where init-system-helpers gets upgraded before systemd, and to make i-s-h
backportable to Jessie.
Closes: #830982
