Would uefi handle more then one gpt table while booting? E.g. booting
diffrent efi grub bootloader partitions at one device? Thought about using 
hybrid mbr records with this more gpt tables...

Sry... Made a mistake on using sgdisk parameters.

When working with parted,sgdisk,gdisk,partx and wipefs there came
some questions into been:

Wipefs... Showing more then one label for an whole device with one
gpt tabled partition. (E.g. GPT and PBMR labels with an sector offset)
The sense would be, wipefs is showing gpt data instead of filesystem data 
like mentioned in the manpages?

Sector alignment... When i am using SI instead of EIC alignment 
then it would mind to align it to e.g. 2000 instead of 2048bytes?
Neither of the tools, provided by gnu and apple, let me change the
value with an result in the mode settings?

Sector size... I distinguiѕh between sector alignment value
and physical/logical sector size. Is there a possibility to set the
logical sector size? Because, btrfs takes raw devices, also. When
i create a software raid with btrfs, it should have the possiblity
to align the sectors on the fly. Then logical=physical sector size
should fasten the device I/O?

Thx and much values!
