[arch-general] [OT] What is wrong with DBus anyway?

[Raghavendra Prabhu]

I never had dbus crashing anytime.. Regarding communication channels - there
are two types in dbus - one is system and other is userland.. So dbus
provided something for userland apps which could not use IPC for some
reason.

Another main reason as pointed above, it is general pub/sub system - which
wasn't there before, and it is quite generic in that publishing to an
interface works(need not know underlying stuff).

Regarding bad experiences with dbus, it is the application's fault. If app
is having problem with dbus, then compile that app without dbus. If that
doesnt work then ditch that application. (send flame mail to app creator :)
if you are over pissed)
