The first step here is to realize that "packages" implement "functions" (or "facilities", or "virtual services").

Often, most usually, and as normal case, the "function" name is impliedby the package that implements it, so that every package automatically and implicitly provides its function. (That's how language works, isn't it)

Like, the package "udev" provides the function "udev".

However some packages are declared to *provide* aditional functions, such that for example package "eudev" provides "udev"; that is simply the promise for the dependecy system that when you install "eudev" you'll get all API and ABI that is originally provided by "udev".

It's not an uncommon or new thing, and I can't answer why dpkg lodges an error message for it. That whinging is new to me. Possibly it just whinges about that your system has both "udev" as a package and some other package, perhaps eudev, that is declared to provide "udev". Though I'd be eager to learn better or more exactly about this.

Thanks.
Yes i am also have eudev, and its working

Mmm; it's rc-update that complains.... That's a different place with kindof the same structure.

I'm guessing you have two files in /etc/init.d where one says it provides "udev" and the other that it provides "$udev" (where the latter is a virtual service name). Probably you don't need both, perhaps it's a matter of keeping "eudev" and moving away "udev" from there.
