It's not about not being available in normal use, it's because switching the library's implementation is fragile -- especially if systemd's prerm fails which it's notorious to. This will make apt fail, and apt happens to be the very package supposed to fix such a problem. > I expect that apt will eventually switch to using libglib's dbus support, > once we implement a daemon, but that's a bit off, and that stuff might live > in a separate binary to not pull in libglib on systems that don't need a > daemon. Would you accept a patch to move the inhibit function to a small separate binary? That'd be a very simple solution.
