Hello,

I am rather new to FAI. But I am impresst by this great tool.
Especially by the documentation that commes with it.

But I am suprised I do not find any working example on how to set up a 
simple RAID 1 with UEFI boot.

I read all the discussions in this mailinglist (found two threads 
dealing with the problem).

I am aware that RAID and UEFI do not get together well due to the fact 
that the RAID information is not available at boot-time and [grup] has 
to deal with a device [sda] rather than with a partition [md0]. Futher 
more [grup] needs a partition with partition type [vfat].

I can imaging a solution with FAI that needs special one-time treatment 
done manualy after FAI hast terminated, but this kills the aim of FAI : 
A=fully, A=automated .

so my question is:
- Can any one supply a solution that manages RAID 1 with UEFI at the 
same time?
   (I would be sadisfied with a solution where the Partition used by 
UEFI-boot is *not* on a RAID.)

   or

- Is it realy just not so easy to get RAID and UEFI to work together 
because FAI was established at a time where there was no UEFI boot. 
Hence the stucture of FAI is not intended to solve this in the first 
pace. Attemts to solve this will result in rather ugly workarounds?

I'd appreciate any helpfull reply.
And thanks again for this great tool.
