Subject: activation: add /lib/dbus-1/system-services to the search path for services
X-Git-Tag: dbus-1.4.14~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d837d937c589e0fb11e4da8d6173ec14f121d1fa;p=thirdparty%2Fdbus.git

activation: add /lib/dbus-1/system-services to the search path for services

In order to allow D-Bus usage during early boot (where /usr is not
accessible) also search for bus activation files in
/lib/dbus-1/system-services/. This is only a first step in the right
direction, before we really can boot without /usr we'd need to move all
current activation files (or possibly replace
/usr/dbus-1/system-services to a symlink to
/lib/dbus-1/system-services).
