As of F16 new installs use GPT. The future is now!

UEFI boots from a vfat partition so yes, there is enough space (we already support EFI) but it isn't stored in the MBR.

Completely the opposite! After getting burned bad by that corruption bug a few years ago, and trying to untangle spaghetti PVs scattered needlessly by lazy sysadmins, I avoid LVM when I can. For most Linux installs it's needless complexity and a bad temptation.

Yes, I'll still use it for a server that needs it. But with fast SSDs and contiguous 3TB for $120, I haven't needed it for 4 or 5 years.

LVM is not an unalloyed win, to say the least, and requires some skill to set up correctly. See http://serverfault.com/questions/279571/lvm-dangers-and-c... for some issues.

I'm not quite sure it's that bad, i've never had a server failure where LVM was a factor but I've had many times where LVM has saved my bacon with the ability to live upsize filesystems. I could see that on a desktop without battery backed write cache that LVM is probably not useful and trying to shrink live filesystems is fraught with peril but in the server use case it is very useful.

I always disable LVM on my own systems, I don't feel as though I'm missing out.
