On the macbook version works good.. But if you want to mount manually, apparently it mount the sd-card on /dev/uba1, but is for the macbook verison and maybe diferent in the other version..by Sacra - [OLD] - Installed Mode
I think is "apt-get upgrade"..by Sacra - Announcements of Newest Features
I had the same problem... But i tried a temporal solution and it's working.. When you install the system, before you configure your new system, you can make a backup of the 'original' initrd.. Then configure the system and finally put the 'original' initrd in the lilo.conf.. So you'll boot your system like the first time.. Sorry for my bad english...by Sacra - MacBook version
