+I've had issues in the past because Linux considered LVM just one logical
+disk and I think the average user would eventually have the same problem as
+well.  I think moving to LVM as the default will create too many complaints
+and support requests in the end.
+
+A long time ago I had a system with 6 SCSI disks, each 1.2GB.  The system
+was fairly useless with the single disks, but using LVM I had 1 disk of
+reasonable size.  I ran the system for about a year with no problems, but
+then 1 of the disks failed.  Normally this would be a medium inconvenience,
+because I would just have to restore the files from that one drive to
+another drive. However, with the LVM, I lost the ability to read the entire
+LVM.  I had to restore the entire system, which was a much bigger pain.  I
+also could not obtain a disk of the same small size for a reasonable price,
+which I was told would make the problem even bigger.
+
+If I had used some redundancy, then I might have been able to restore the
+one disk, but I was a novice user and didn't understand the need.  I think
+that most users who use the defaults and probably novice users, or at least
+will be after Mageia takes off.  I think LVM support is a must, but I think
+making it the default, without also making some redundancy the default, will
+cause more problems than it solves.
