Number1: Either install and extract overwrites the previous Android OS.
Number2:The kernals can only be mounted and installed /and and again the problem of over writing each other

I am struggling to find a way to do this without backing up and repartitioning the flash storage.
Theorically it is possible a solution like this:
  • Use a big optFS (Maemo's /home), at least 4GB but bigger is better
  • Create on it an android directory with one subdirectory for each nitdroid version you want to install (i.e. Nitdroid 0.0.9, Gingerbread, Gingerbread mido's version)
    sudo gainroot
    cd /home
    mkdir nitdroid-container
    cd nitdroid-container
    mkdir froyo-1
    mkdir gingerbread-1
    mkdir gingerbread-2
    cd /home
  • Mount the directory
    mount -o bind /home/nitdroid-container/froyo-1 /and
    and install your Nitdroid (i.e Froyo) as usual.
    Dismount directory when finished
    umount /and
  • Mount the directory
    mount -o bind /home/nitdroid-container/gingerbread-1 /and
    and install your Nitdroid (i.e Gingerbread) as usual.
    Dismount directory when finished
    umount /and
  • Mount the directory
    mount -o bind /home/nitdroid-container/gingerbread-2 /and
    and install your Nitdroid (i.e mido's Gingerbread) as usual.
    Dismount directory when finished
    umount /and
  • Modify the multiboot's script to add a "pivot_root to subdir" capability
  • Create 3 multiboot's boot scripts (i.e. 33-froyo.item, 44-ginger1.item, 55-ginger2.item) with correct options on them

The most difficult step is to enhance multiboot's capabilities, but it is an rather easy job for people with linux's script skills
