dbus-broker - Linux D-Bus Message Broker
CHANGES WITH 13:
* The --verbose command-line switch was dropped from both the broker
and the launcher. Its behavior is now the default.
* Fix a startup dead-lock with systemd NSS plugins. This requires
setting the SYSTEMD_NSS_BYPASS_BUS environment variable, so
libnss_systemd.so will skip recursive bus-calls.
* Read /etc/{passwd,groups} early on from the launcher to
pre-initialize the nss-cache. This allows startup on properly
configured systems without ever calling into NSS. Furthermore, in
case this does not resolve all required usernames, the launcher will
loudly log any call into NSS, to better debug early dead-locks in bus
startup code.
Note that this new mechanic overrules /etc/nsswitch.conf for the
launcher. However, this is only made based on the assumption that
if an entry is present in /etc/{passwd,groups}, it better be a valid
entry. If an entry is not present, the launcher will still correctly
call into NSS.
