The system I'm building for is a tiny linux VM, using busybox for most utils
and definitely does not have glib included.
But, even the system I was building on, an Ubuntu system, did not have glib
installed by default -- I had to install it with apt-get.
For general purpose VMs, the new libs are probably a non-issue. For virtual
appliances, trying to stay lean they are a bigger deal. Especially for
security appliances, which try to minimize the included code.

I did build without-x. According to ldd, the libraries in current builds
not present in "guestd" are: libvmtools.so.0, libgmodule-2.0.so.0,
libgobject-2.0.so.0, libgthread-2.0.so.0, librt.so.1, libglib-2.0.so.0,
libpcre.so.3. I think all the libg* libraries are part of glib, obviously
libvmtools just moves code that used to be in a single binary. Are librt
and libpcre dependencies of glib?

Yeah, good point, I didn't strip anything yet, that's done as part of the
system build. I went back and did that, and it's they are much smaller
now.
And memory overhead, at least for the system service, hasn't really changed

For now, I moved back to the last version that still had guestd. I didn't
want to mess with all the new libraries. Not a great solution, but it was
simple. Maybe in the next rev I'll add glib, etc.
Thanks for the response.
