Using a newer kernel (than wheezy) and dracut

[Carsten Aulbert]

Hi all

(I hope this was not covered recently on this list as I have not paid
too close attention)

our latest machines will not work with the current wheezy kernel (nor
the one FAI 4.0.8 is using during installation) [1]. Thus we inserted
the latest grml kernel according to

http://wiki.fai-project.org/wiki/Grml_Kernel

however, installations always stopped prior to mounting the NFSroot with
"mount.nfs: Protocol not supported". It seems that one needs to manually
add the kernel drivers nfsv{2,3,4} among others when using a kernel 3.6
or later *or* upgrade to a much newer dracut than the one in wheezy
(020) [2].

A simple backport of the current 034 version from jessie works fine as well.

Hopefully this will help others to save some time ;)

Cheers

Carsten
