preserve <> lazyformat (was Re: SUMMARY: disk config's preserve option does not work)

[Holger Levsen]

Hello faiworld,

I used to use preserve, but I found it to complicated: 

first: after setting up the computer for the first time with FAI, i have
to modify disk_config to include the preserve option.

second, I have to compute the partition number, that's not too
complicated, but I may fail. 

That's why I use "lazyformat" now: the partition gets formatted the
first time the new partition scheme is used, after that, partitions
marked "lazyformat" do'nt get formatted anymore. voila!
