Disk size:<br>
<br>
On my x86-64 Debian laptop, the shared libdbus is 280K. All the dbus-*<br>
tools are linked to it dynamically, except for dbus-daemon (408K) and<br>
dbus-daemon-launch-helper (280K). So the most you could possibly save<br>
like this would be to cut up to 280K each off the on-disk size of<br>
dbus-daemon and d-d-l-h (in practice it'll be less, because I'm sure<br>
they don't use all of libdbus). Sure, that would be an improvement, but<br>
I'm not sure the cost/benefit ratio is significant (particularly if<br>
dynamic linking overhead eats up some of the benefit).<br></blockquote><div><br></div><div>For tiny embedded systems, 500K disk space savings actually sounds pretty good. Memory sharing between dbus-daemon and libdbus-1-using apps sounds good too even if it's only 280k-ish (the more memory we can give back to the application, the better etc.). On a desktop system, sure, there's no point :-)</div>
