--- Comment #3 from gross <grossws at gmail.com> ---
As I see in
http://svn.savannah.nongnu.org/viewvc/sysvinit/trunk/src/init.c?annotate=159&root=sysvinit
(around line 1146) sysvinit set SIG_IGN for SIGQUIT. 

It seems that OpenRC isn't an init (it provides rc but not /sbin/init), so it's
behavior depends on underlying sysvinit/bsd-init.

I don't see any SIGQUIT handler in upstart (and libnih), so it should behave
like systemd, with pid 1 core dumped and broken system after `kill -SIGQUIT 1`.

It's not a security problem, of course. It's at most an usability problem. Is
default core dump required for debugging systemd? Is there any reason not to
ignore it?
