Hi,
I have hit the next stumbling block (show stopper):
src/shared/util.c: In function 'glob_exists':
src/shared/util.c:4376:36: error: 'GLOB_BRACE' undeclared (first use in this function)
src/shared/util.c:4376:36: note: each undeclared identifier is reported only once for each function it appears in
I see this is and non-standard posix extension. I guess that is it for systemd for now then.
