FWIW, I downloaded openSUSE just to give it a whirl.  It has a very nice 
install process with nice screens and is fairly easy to follow.  By default 
it creates partitions for / and /home as well as swap and does not use LVM.

As the install completes it offers to run online updates.

Too bad that after all of that it left the / partition 100% full and there 
was no easy way to increase the size of /.  With LVM it would have been a 
snap.  Oh well, I suppose all distros have their warts.  Will have to try 
installing again sometime.  Still would like to experience their kernel 
update process.
