Comment:

 I cannot reproduce this. First, bind10 now detects that another copy is
 running and will refuse to start a second copy:

 {{{
 $ ../sbin/bind10
 INFO [b10-init.init]: BIND10_STARTING starting BIND10: bind10 20110223
 (BIND 10 20130529)
 DEBUG [b10-init.init]: BIND10_CHECK_MSGQ_ALREADY_RUNNING checking if msgq
 is already running
 DEBUG [b10-init.pycc]: PYCC_LNAME_RECEIVED received local name:

 FATAL [b10-init.init]: BIND10_MSGQ_ALREADY_RUNNING msgq daemon already
 running, cannot start
 FATAL [b10-init.init]: BIND10_STARTUP_ERROR error during startup: b10-msgq
 already running, or default socket file not cleaned - cannot start
 }}}

 Second, if I manually start the config manager again and exit it, it does
 not seem to overwrite anything:

 {{{
 $ cat b10-config.db
 {"Init": {"components": {"b10-auth": {"kind": "needed", "special":
 "auth"}, "b10-stats": {"kind": "dispensable", "address": "Stats"},
