I did ask google the
question, "udev hotplug" and the great grandfather
google gave me only one mail that said udev can do
the
job of hotplug.
To use plug and play with 2.4 Linux kernels, they
brought out the hotplug scripts. 2.4 Linux kernels use
devfs. So, when you plug in any device, say a USB pen
drive, for example, you will need to look in dmesg
output to see what device file it was, /dev/sda1 or
whatever and mount it manually or use hotplug.
In 2.6 Linux kernels, udev is used. In user-space,
there is a udevd daemon that gets notification from
the udev in kernel-space when devices are
attached/removed.
ps -e | grep udev
So, all plug and play devices are automatically
mounted.
Anyway I am quite sure udev is somewhat buggy being
new.
udev is not new. It has been there from 2.6 Linux
kernels. Please read Grek Kroah-Hartman's paper
presented in OLS 2003:
http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html
http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev-FAQ
I use it on Debian, Fedora, Ubuntu and don't have any
problems with it.
Regards,
SK
