I'm fine with that. But:

It seems be that sd_listen_fds() is new in v209. It was backported to
v208 in openSUSE 13.1. So there should be some detection if
sd_listen_fds() is really available. Looks like this patch removes the
check.

I get this from pkg-config:

root@optiplex:/work/olaf/13.1/github/olafhering/xen.git # pkg-config --cflags 
libsystemd-daemon ; echo $?

0
root@optiplex:/work/olaf/13.1/github/olafhering/xen.git # pkg-config --libs 
libsystemd-daemon ; echo $?
-lsystemd-daemon 
0
