But that doesn't seem happy with MBR type disks.  You don't need GPT
unless the disk is bigger then 2 Gigs and 4k-sector drives start at
750G, at least in the laptop sizes.   gdisk -l says this about a
layout created by the Centos installer:

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present


***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format.

Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.
Disk /dev/sda: 262144000 sectors, 125.0 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 4E46CCD4-4010-401E-84A8-020B674DA64B
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 262143966
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048         1026047   500.0 MiB   8300  Linux filesystem
   2         1026048       262143999   124.5 GiB   8E00  Linux LVM


Is something really wrong with it?
