XFS FAQ - out of date?

[Viktor Trojanovic]

Hi,

I just tried to do a fresh install of Arch Linux using XFS for my root 
system. According to the xfs.org FAQ, this is supported. But it didn't work.

I later found (very few) sources that confirmed that Grub is not 
compatible with the current XFS level 5, that SuSE created a patch for 
the problem but it wasn't adopted upstream. If this is true, consider 
updating the FAQ. If it is not true, I would very much appreciate some 
hints how to do it properly.

Thank you.

Best regards,
Viktor
