Hi Elizabeth,

You are right that most of the steps are from LiveCDCustomization wiki 
page. I am wondering if those are tested for 12.04 and/or Xubuntu.

After some searching in logs I think this has to do with lightdm: gvfs 
is mounted in the lightdm /var/lib folder

Looking more into this... :)

Cheers,
Angelos
