The NFSROOT variable and extrbase task.

[Toomas Tamm]

Hello!

I was writing a hook to replace the extrbase task. While I was not
directly hit by this, I noticed that extrbase makes use of the variable
$NFSROOT if the condition [ $do_init_tasks -eq 0 ] (as well as some
others) is met.

However, in /usr/sbin/fai the variable NFSROOT is assigned if 
[ X$action = Xdirinstall ] .

Is there a possiblity that extrbase gets called with unset NFSROOT when
it is required? Or are the two situations mutually exclusive?

I am using the latest FAI from experimental.
