So, a number of people have complained over the past few years about the
fact that /sbin/hotplug was a shell script.  Funny enough, it's the
people on the huge boxes, with huge number of devices that are
complaining, not the embedded people with limited resources (ironic,
isn't it...)

Anyway, attached below is a replacement /sbin/hotplug written in c.
Compiling it with klibc gives you me the following size:
$ size hotplug 
   text    data     bss     dec     hex filename
   4149      28      20    4197    1065 hotplug
$ ls -l hotplug 
-rwxr-xr-x  1 greg users 4636 Nov 18 15:08 hotplug

Which is smaller than /bin/true on my boxes (and /bin/true is linked
dynamically, this is a static binary.  Linked dynamically, it's still
smaller than /bin/true.  gnu programs, go figure...)

I'll be putting this all togther in a "hotplug-ng" type tarball, as I
slowly replace the existing hotplug scripts with rewrites based on the
fact that we've learned things over the past 4 years, and dropping
support for 2.4 and previous kernels.  But for now, have fun with this
program.

Oh, and yeah, I know I need to fix up the fact that if /dev/null isn't
present, we should create it ourselves and go from there.  That's next
on the list after putting it all in a project.

thanks,

p.s. the list.h and logging.h files come from the udev project, if you
want to build this yourself.
