    (scripts, modules.conf, etc.)  This is not a task for udev.
 
+Q: But I love that feature of devfs, please?
+A: The devfs approach caused a lot of spurious modprobe attempts as
+   programs probed to see if devices were present or not.  Every probe
+   attempt created a process to run modprobe, almost all of which were
+   spurious.

 Q: I really like the devfs naming scheme, will udev do that?
 A: Yes, udev can create /dev nodes using the devfs naming policy.  A
    configuration file needs to be created to map the kernel default names
-   to the devfs names.  See the initial udev.conf.devfs file in the udev
+   to the devfs names.  See the initial udev.rules.devfs file in the udev
    release.  It is the start of such a configuration file.  If there are
    any things missing, please let the udev authors know.

 A: udev will be placed in initramfs and run for every device that is found.
    Work to get this implemented is still underway.
 
+Q: Can I use udev to automount a USB device when I connect it?
+A: Technically, yes, but udev is not intended for this. Projects that do
+   automount hotplugged storage devices are:
+     * Usb-mount http://users.actrix.co.nz/michael/usbmount.html
+     * devlabel http://linux.dell.com/projects.shtml#devlabel

+   /udev/pendrive       /pendrive       vfat    user,noauto             0       0
+
+   This means that users can access the device with:
+   $ mount /pendrive
+   And don't have to be root but will get full permissions on /pendrive.
+   This works even without udev if /udev/pendrive is replaced by /dev/sda1

 Q: I have other questions about udev, where do I ask them?
 A: The linux-hotplug-devel mailing list is the proper place for it.  The
    address for it is linux-hotplug-devel@lists.sourceforge.net
