I'm using the 20130207 install iso.  This is to enable me to get a
*REALLY* predictable NIC name, namely eth0, but I digress.  The 2
warnings I get are...

1)
> WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util
> fdisk doesn't support GPT. Use GNU Parted.

  I've repartitioned it 3 or 4 times, but it still comes up with that
error when I fire up fdisk.  Is it a problem, and if so, can I dd a few
sectors to remove whatever it's complaining about?


2)
> The device presents a logical sector size that is smaller than the
> physical sector size. Aligning to a physical sector (or optimal I/O)
> size boundary is recommended, or performance may be impacted.

  The fdisk "p" command gives the following output header

> Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
> 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
> Units = sectors of 1 * 512 = 512 bytes
> Sector size (logical/physical): 512 bytes / 4096 bytes
> I/O size (minimum/optimal): 4096 bytes / 4096 bytes

  The fdisk default seems to be to start partition 1 at sector 2048.  I
don't know the hardware side of disks.  Is that OK.
