Subject: core/manager: print info about interesting signals
X-Git-Tag: v209~572
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=a9244623f785f504f799407b0228dea9655e24cb;hp=41aef6fc747a3b5b8bf47faa468881be16509c66

core/manager: print info about interesting signals

Information about signals which are not routinely received by systemd
are printed at info level. This should make it easier to see what is
happening in the system.
