The following Variables do exist in FAI (example values included):

Please do not edit that much, without contacting Mrfai. Currently it's my private list of variable and comments.

type: int = internal use only; CS used in config space (often defined by *.var)

Which variables are needed inside the nfsroot, so the install clients can use them? (maybe write them into fai-client.var or nfsroot.var). Then do not copy fai.conf into the nfsroot any more.
