wheezy live hdd is not persistent

["upiter77@lycos.com" <upiter77@lycos.com>]

hi

I've created wheezy live hdd with XFCE and I'm using this command to make it persistent, before build:

lb config --bootappend-live "persistent hostname=thinA11 username=sta quickreboot locales=de_DE.UTF-8 keyboard-layouts=de utc=no timezone=Europe/Amsterdam"

After build I've created an additional ext2 home-rw partition, but it is still not persistent. 

BTW I didn't have this problem on squeeze live.

greetings
Piotr
