Directory not removed when driver is unloaded.

Directory not removed when driver is unloaded.

[Frederick (Rick) A Niles]

OK first off let me state the disclaimer that I'm clueless about what
I'm doing with udev.  So please don't flame me too hard that I'm doing
it all wrong.

Short description: I've managed to get udev to work very well for me
with one exception.  The directory that gets created for my devices
under /dev does not get removed when the driver exits and then when the
driver is reloaded the permission of that directory are wrong.

Long description: 

I'm using a Fedora Core 3 system and I have added the minimal sysfs
stuff to my driver.  It's using the "10.FC3.7" version of the udev
package.

/etc/udev/rules.d/90-foo.rules:
KERNEL="foo.bar",         NAME="foo/bar"
KERNEL="foo.baz",         NAME="foo/baz"
======


/etc/udev/permissions.d/90-foo.permissions:
foo/*:root:users:0666
foo:root:users:0755
======


(BTW, these aren't the real name for the driver, just for illustration)

First time I load the driver, the device files get created and the
permissions are correct.

When I remove the driver the directory changes permission to 0000 and
never changes again, even when I reload the driver.

The files are not removed as expected when the driver is unloaded.

So either:

 (1) I'm doing something wrong with my rules and/or permissions file

or

 (2) There was a bug in udev for this older version and hopefully it's
fixed now...

I appreciate any guidance you can give.

Thanks,
Rick Niles.

What exact version of udev are you using?

What does 'udevinfo -V' return?

And yes, upgrading to the latest version might be a good place to start
:)

thanks,
