In udev terminology, »hotplug« means that the device is added to the system after the udev subsystem has been running for a while. »Coldplug« is what happens when udev boots, in order to handle devices that have been part of the system all along. Think »hard disk in a bay inside the actual box« vs. »USB stick« -- both of them show up in /sys and /dev in essentially the same way, but the one was already there when the system was booted and is likely to stay put until it is shut down, while the other may come and go arbitrarily. The idea is to use the same mechanism (udev) to manage both flavours of device, which makes a lot of sense to me. As Jorge correctly remarks, there used to be a system called »hotplug« which was basically a precursor of udev. I don't recall a »coldplug« subsystem. Anselm -- Anselm Lingnau ...
