Interestingly my android install does not seem to use the ext3 partition - looks like I wasted some sdcard space making that?

This is an install from ran's cupcake image:-

# mount
rootfs / rootfs ro 0 0
tmpfs /dev tmpfs rw,mode=755 0 0
devpts /dev/pts devpts rw,mode=600 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
tmpfs /sqlite_stmt_journals tmpfs rw,size=4096k 0 0
/dev/block/mtdblock6 /system jffs2 ro 0 0
/dev/block/mmcblk0p1 /sdcard vfat rw,nosuid,nodev,fmask=0000,dmask=0000,allow_utime=0022,codepage=cp437,iocharset=iso8859-1 0 0
/dev/block/mtdblock7 /data yaffs2 rw,nosuid,nodev 0 0
