Novell and its SUSE buddies come right out and say, "This is an unsupported, open-source only, preliminary edition of SUSE Linux that contains bleeding-edge packages and represents the latest development snapshot."
In short, do not, we repeat do not, run this on a production system.
Fool that I am, after I spent a day working with SUSE 10.1 on one of my test systems, I started swapping it in on my production SUSE 10 Linux desktop.
Why? Because I really like it, and I, as something of a Linux expert, can steer around problems that may knock most users over.
Now if you want to follow in my footsteps, be certain to read the Most Annoying Bugs list.
The only one I found troublesome was that the Xen module in YaST2--SUSEs management system--wont let you setup a Xen VM (virtual machine) properly.
Even so, if you know Xen and youre not afraid to get your hands dirty, its not a deal-breaker.
