So it's hard to "reconnect" if DBUS goes down for any reason ?
That doesn't really speak good for DBUS, because it is sure that for one
reason or another it will go down at some point.
Caliming that DBUS can never be restarted is putting your head under the
sand. Bugs just happen, dbus might explode for who knows what reason,
does it mean the machine should implode as well ?
Sure. All software has bugs. I submit that it's far more likely for the kernel (or more specifically, drivers) or hardware flaws than DBus.
Good applications are usually built to reconnect when a transport they
use becomes unavailable. if some network switch breaks for a few seconds
down the road my connections have a good chance of surviving and if when
connectivity is back things keep going as if nothing happened.
Right. You know how basically every mail client explodes error dialogs when your network connection happens to be broken for a bit? Imagine those error dialogs popping up in your file browser because suddenly HAL went away during a software upgrade. Not cool.
If it is a huge task we have worst problems, we have apps badly
engineered.
No. Applications are not engineered to survive a kernel restart either.
Just think of DBus as a kernel extension. Or from another view, there is precedent even in traditional Unix for privileged userspace processes - think init. Just pretend that DBus happened to be implemented in the init process instead of as pid 2.
