Much ado about absolutely nothing. The default is now to not enable 
ctrl-alt-backspace. You can easily turn it back on if you must have it, 
either by a line in an xorg.conf or a xkb setting, iirc. Also, its an 
upstream X change, not an Ubuntu change, Fedora 11 will feature the same 
behavior.

I believe the forthcoming OpenSUSE version patched around the upstream 
change different, instead making the first press of ctrl-alt-backspace 
sound a system bell, then if you hit it again, it does what its always done.

Nah, its not so bad, been running it non-stop for over a year on 
multiple systems. There have been occasional issues, but nothing that 
significant for most use cases that hasn't been fixed rather quickly. 
Fedora 11 is shipping w/ext4 as its default file system, and its held up 
quite well through the development cycle. Helps that Red Hat actually 
employs people who work on file system code to be confident in making it 
the default though... (sorry, couldn't resist).

ext4 is pretty low-risk for MythTV-type data, but one of our file system 
hackers at Red Hat who works on both ext4 and xfs and is a mythtv user 
himself still recommends xfs over ext4 for a mythtv storage volume, but 
only by a slight bit these days.
