problem with sync_server and CYRUS_SERVICE

[Nic Bernstein]

Folks,
I have been building and using Cyrus IMAP since 1995, but I've just run 
into an issue I've never encountered before.  I've had the same issue 
with 2.4.16 and 2.5, both built from sources retrieved via Git.  This is 
on Ubuntu 12.04.01 LTS, in LXC containers on an Ubuntu 12.04.01 LTS host.

When I start cyrus I see this in syslog:

    Oct 23 19:08:26 mailbox master[1323]: about to exec /usr/lib/cyrus/bin/sync_server
    Oct 23 19:08:26 mailbox sync_server: could not getenv(CYRUS_SERVICE); exiting
    Oct 23 19:08:26 mailbox master[1313]: process 1323 exited, status 70
    Oct 23 19:08:26 mailbox master[1313]: unable to setsocketopt(IP_TOS): Operation not supported

I don't think the getenv problem is related to the IP_TOS issue, is it?  
I've checked all around for what can cause the getenv(CYRUS_SERVICE) 
issue, which was typically (in the old days) interference from inetd, 
but that can't be the problem here, since there is no inetd running on 
the container or the parent host.

/etc/cyrus.conf looks like this:

    START {
    	recover		cmd="/usr/sbin/cyrus ctl_cyrusdb -r"
    	idled		cmd="idled"
    	tlsprune	cmd="/usr/sbin/cyrus tls_prune"
    	syncserver      cmd="/usr/lib/cyrus/bin/sync_server" listen="csync"
    }

    SERVICES {
    	imap		cmd="imapd -U 30" listen="imap" prefork=0
    	pop3		cmd="pop3d -U 30" listen="pop3" prefork=0 maxchild=50
       	lmtp		cmd="lmtpd" listen="lmtp" prefork=1
       	sieve		cmd="timsieved" listen="sieve" prefork=0
    	notify		cmd="notifyd" listen="/var/run/cyrus/socket/notify" proto="udp" prefork=1
    }

    EVENTS {
    	checkpoint	cmd="/usr/sbin/cyrus ctl_cyrusdb -c" period=30
    	delprune	cmd="/usr/sbin/cyrus expire -E 3 -D 60 -X 60" at=0401
    	tlsprune	cmd="/usr/sbin/cyrus tls_prune" at=0401
    	squatter_1	cmd="/usr/bin/nice -n 19 /usr/sbin/cyrus squatter -s" period=180
    	squatter_a	cmd="/usr/sbin/cyrus squatter" at=0117
    }

and /etc/services contains this:

    # Local services
    lmtp		24/tcp				# Cyrus IMAP LMTP transport
    csync		2005/tcp			# Cyrus IMAP replication

Any thoughts?

Cheers,
     -nic
