Add global command line option to disable default devices.Should -readconfig imply this?Hmm, not sure. Why do you think this would be useful?Here is my thinking: if you used -writeconfig, your machine description is (at least in theory) entirely included in the config file including (again in theory) the default devices.
The default devices are *not* included by in the file created by -writeconfig. So I tend to thing -readconfig should not automagically turn on -nodefaults to avoid unpleasent surprises for users.
Devices created via -readconfig are treated like devices created via [device] sections in the config file. So it doesn't matter whenever you configure your isa-serial device via command line or config file, in any case it will make qemu not create the default serial port.
cheers, Gerd
