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:
Quote:
[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:
Quote:
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?
