pull request for setup-storage

[Thomas Neumann]

Hello Thomas, Kerim and who else is listening


PullRequest https://github.com/faiproject/fai/pull/17

"Please review this patchset to get rid of the global variable %FAI::disk_var
 and the implicit usage of %FAI::configs in find_boot_mnt_point().

 Patches can be applied one after another, alls patches verify successfully
 against the unit test. The final patch requires a modification of the setup-
 storage script. (included in the patch) The unit test results were generated
 by an unmodified setup-storage 1.6.

 (This is one of the steps necessary to turn Fstab.pm into a proper module
  with it's own namespace.)"

My branch with the changes is located at
https://github.com/ThomasNeumann/setup-storage/tree/refactor_Fstab.pm


The long term goal would be to get rid of all global variables and decouple 
all modules in order to make it more obvious what is going on.
