ubuntu serve - cyrus fails to start

[lowpass]

Ubuntu server 14.04.2
Linux poseidon 2.6.32-042stab088.4 #1 SMP Thu Apr 3 17:41:05 MSK 2014
x86_64 x86_64 x86_64 GNU/Linux
cyrus-imapd-2.4 (2.4.17+caldav~beta9-3)


After rebooting my server yesterday (after a package upgrade having nothing
to do with cyrus afaict) cyrus-imapd is silently failing. The logs complain
that the socket does not exist:

status=deferred (connect to poseidon.xxxx.com[/run/cyrus/socket/lmtp]: No
such file or directory)

Indeed, there's nothing cyrus related in /var/run (/run). In
/etc/init.d/cyrus-imapd:

NAME=cyrmaster
DAEMON=/usr/sbin/${NAME}
PIDFILE="/var/run/${NAME}.pid"

Attempting to manually start it tells me nothing:

# service cyrus-imapd status [or start]
[no response]


None of the cyrus or postfix configs have been altered recently. I see
nothing in any log to suggest a problem upon startup.

}

Note the lmtp/lmtpunix lines. At some point i made a change, then a second
one. Unfortunately, that was a long time ago and i stupidly didn't leave
any comments here. However, everything has been working well for several
years.


/etc/imapd.conf:

configdirectory: /var/lib/cyrus
proc_path: /run/cyrus/proc
mboxname_lockpath: /run/cyrus/lock
lmtpsocket: /run/cyrus/socket/lmtp
idlesocket: /run/cyrus/socket/idle
notifysocket: /run/cyrus/socket/notify
syslog_prefix: cyrus

I do have socket and lock dirs under /var/lib/cyrus but they were last
modified several years ago and seem to be left over from some other config.
Other dirs there have seen more recent activity. Everything seems to be
pointing towards the socket & lock dirs being created under /run but
there's nothing there.

I found this bug report from the previous version which seems to be related:

http://www.ubuntuupdates.org/package/core/trusty/universe/base/cyrus-imapd-2.4


Finally, the following is from apt-history log for the update done
yesterday. I've included everything regardless of whether i know it's of
consequence. I also rebooted the server afterwards so it's entirely
possible that the package upgrades have nothing to do with the problem with
cyrus.
