udev question

I'm trying to learn about how device management works in Linux and I'm a bit confused about udev.

I'm running 2 different VM's - 1. Ubuntu 11.04 & 2. Fedora 15

On the Fedora 15 VM when I run the mount command I see the following:

[dtest@Fedora-VM1 udev]$ mount
/proc on /proc type proc (rw,relatime)
/sys on /sys type sysfs (rw,relatime)
udev on /dev type devtmpfs (rw,nosuid,relatime,size=1024144k,nr_inodes=213591,mode=755)
On the Ubuntu 11.04 VM I see the following:

dtest@ubuntu-P5K:/etc$ mount
/dev/sda2 on / type ext4 (rw,errors=remount-ro,commit=0)
proc on /proc type proc (rw,noexec,nosuid,nodev)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
none on /dev type devtmpfs (rw,mode=0755)
The main thing I am confused with is how udev is handled differently between Ubuntu and Fedora. On Fedora it shows, "udev on /dev type devtmpfs", but on Ubuntu it shows "none on /dev type devtmpfs".

I can't find mention of udev anywhere in the output of the mount comnmand when run under Ubuntu. Can somebody help me understand how this is handled?

These names on first column: "udev" and "none" are arbitrary, it can be any text. It is not taken into account during mounting.
