Just a small terminology change...  Distros are now using udev, not 
devfs--devfs has been deprecated.  From: 
http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev-FAQ

Q: How is udev related to devfs?
A: udev works entirely in userspace, using hotplug events the kernel sends
whenever a device is added or removed from the kernel. Details about
the devices are exported by the kernel to the sysfs filesystem at /sys
All device naming policy permission control and event handling is done in
userspace. devfs is operated from within the kernel.

Everything else you said is basically correct (although, technically, 
the device entries are not deleted--the entire in-memory filesystem on 
which the devices were created disappears).
