This is my first HOWTO, and I'll make this quick and less painful.
Okay by now you may have noticed that F9 uses weird characters in your /etc/fstab to mount file system. So what are they and how do we manipulate them?
How to find the partition or device associated with the UUID?
UUID=2113dfa3-b0b0-48e5-8764-c842320fa28c / ext3 defaults 1 1
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
UUID=8fa27bec-0676-47e0-9597-c09b169f875c swap swap defaults 0 0
UUID=3150b901-2459-4443-a23b-2d1cfb0276af swap swap defaults 0 0
A command called findfs will help you find your partition
How do you create new UUIDs for a partition?
# findfs UUID=2113dfa3-b0b0-48e5-8764-c842320fa28c
How do we find the UUID of a partition?
# tune2fs -U random /dev/sda8
What is the UUID of my reiserfs partition?
# tune2fs -l /dev/sda7 |grep UUID
Filesystem UUID: 2113dfa3-b0b0-48e5-8764-c842320fa28c
To the best of my knowledge UUIDs are only for ext2/ext3/ext4 file systems.
What does man uuid have to say about this?
The UUID library is used to generate unique identifiers for objects that may be accessible beyond the local system.
Hope this helps
