So, dbus is not needed there. > Is apt the only way to know if dbus is redundant? No, but it's an easiest one. Hard one would be to answer "what function this server serves", following by "what software performs said function", following by "what the software in question really needs to be operational". Requires knowing your software and a good memory, as usual. > Sorry for not providing the output earlier, but I was hoping for a more > general way to determine on which server dbus can be safely removed. Replace "dbus" with "some annoying dependency", and you'll see that some questions are better left answered by machine, not a human. Reco
