Bug#739318: cyrus-imapd-2.4: Cyrus IMAPd fails to install/start

[Benjamin Redelings I]

Package: cyrus-imapd-2.4
Version: 2.4.17+caldav~beta9-2
Severity: important

Dear Maintainer,

Upon upgrading to 2.4.17+caldav~beta9-2, cyrus imapd fails to install.

It seems that it fails to install because it fails to start:

root at nucleus:/lib/systemd/system# systemctl status cyrus-imapd.service
cyrus-imapd.service - Cyrus IMAP/POP3 daemons
   Loaded: loaded (/lib/systemd/system/cyrus-imapd.service; disabled)
   Active: failed (Result: exit-code) since Mon 2014-02-17 11:46:29 EST; 1s ago
  Process: 6739 ExecStartPre=/usr/bin/cyrus init-helper start (code=exited, status=203/EXEC)
 Main PID: 6183 (code=exited, status=203/EXEC)
   CGroup: name=systemd:/system/cyrus-imapd.service

Presumably this is because systemd support was added in the latest update?

However, /lib/systemd/system/cyrus-imapd.service is a file with paths that are
all wrong.  For example...

ExecStartPre=/usr/bin/cyrus init-helper start
ExecStart=/usr/sbin/cyrmaster -l $LISTENQUEUE -C $CONF -M $MASTERCONF $OPTIONS

Help?
