+DevFs is the Device FileSystem. It's optional starting with LinuxKernel
2.4 and not recommended with LinuxKernel 2.6 as it has been deprecated in favour of [UDev]
.
It is designed so that instead of having to have a central body allocate major and minor numbers (unique identifiers) to devices, you can access them more like a namespace. For example, your serial port /dev/ttyS2 will become /dev/tts/2; console /dev/tty3 will become /dev/vc/3. You can still have support for the old names for software that would otherwise be confused by these changes.
