Udev and hotplug question

In this article, introducing udev, it states:

What is udev?  In a nutshell UDEV is an replacement of DEVFS in user-space using sysfs and /sbin/hotplug. It will create and destroy /dev entries based on the current system configuration. It does this by watching the /sbin/hotplug events on the system, and reading information about these events from sysfs.

So, 1) Is the article severely dated? 2) Is /sbin/hotplug NOT the 'hotplug' I'm thinking it is?  3) Is 'hotplug' still needed / used?

I'm confused  :?

[Edit] For the curious, here's another excellent, clearly written article on udev rules.

Re: Udev and hotplug question

my understanding was that hotplug was completely integrated into udev around version 070, you no longer need hotplug in your deamons list

Ah, so it's #1 -- severely dated article syndrome.

Thanks!

Yeah, it's dated... Udev now uses uevents, which is better in just about every possible way.

Maybe not.  I wonder what version of udev debian is running? Does it even have udev?  Someone said something on the udev mailing list about a month ago, and reported using version 054 (-ish)... yikes.

Re: Udev and hotplug question

Debian Stable uses Devfs, and I think it had Udev 056 in the tree, Debian Sid and Tesing both use Udev though, and they are at 093
