KernelTrap: hotplug-ng, Tiny Binaries for Autoloading Modules

“Greg KH announced his new hotplug based userspace project known
as hotplug-ng. He explains, ‘this collection of code replaces the
existing linux-hotplug package with very tiny, compiled executable
programs, instead of the existing bash scripts.’ He goes on to
add:

“‘But why redo this all in .c code? What’s wrong with shell
scripts? Nothing is wrong with shell scripts, unless you don’t want
to have an interpreter in your initramfs/initrd and you want to
provide /sbin/hotplug and autoload module functionality. Or if you
have a huge box that spawns a zillion hotplug events all at once,
and you need to be able to handle all of that with the minimum
amount of processing time and memory…'”
