Hi all,

I use ubuntu (and recently dual-boot with debian) since April this year.
I don't use windows anymore, in fact i don't need to. I've learned a lot
in Linux in these days. 
Recently I found in ubuntu "/etc/fstab", some UUID for my mounted
partition rather than "/dev/sda1" etc.

I found in internet that it has some advantages.

My question: I have a common partition for data (xfs formatted) which I
want to access from both ubuntu and debian. And that partition should
also automatically mount at boot with user can read/write without going
sudo.

How can I achieve this using UUID naming at "/etc/fstab"?

my current disk structure:
/dev/sda1: reiserfs (ubuntu)
/dev/sda2: swap (common)
/dev/sda3: reiserfs (debian)
/dev/sda4: xfs (common accessible partition)

right now my fstab has the following line for xfs partition, what should
I change ?
/dev/sda4       /media/xfs      xfs     defaults    0  1

Intruders come through windows. Be safe, Use Linux.
