[HOW-TO] Install in BerryBoot

[Bref]

What is wrong?

What I do:

- install xbian on sd card (download image, dd to sd card)
- start pi and let it do its stuff (expand etc)
- login via ssh
- sudo dd bs=1M if=/dev/mmcblk0 of=/pathtomyexternalusbdriveattachedtothepi/out.img
go back to my laptop with my usbdrive.
- sudo kpartx -av /pathtomyexternalusbdriveattachedtothepi/out.img
- sudo mount /dev/mapper/loop2p2 /mnt

now what I get:

bref@Bref-wan:~$ tree -L 2 /mnt
/mnt
├── home
│   ├── @
│   └── @safe
└── root
├── @
└── @safe

meaning something went strange and I cannot go on with changing fstab, mksquashfs etc.

cheers
