Comment 12 for bug 1265192

Can some one please look over and clean up this page:
https://wiki.ubuntu.com/DebuggingUbiquity

I cant understand the deeper debugging section, and how is it different from the "What next section" where it is suggested to launch ubiquity with the -d flag.

How many of these need to be done / which are redundant:
1) the debug-ubiquity command line option
2) the editing of the partman file
3) starting ubiquity with the -d flag
