I am following your guide and following is pasted from your guide
5. Switch from Android to Ubuntu system:
Run su rooted shell, and create a directory as mount point (here is /system/sd) for Ubuntu partition:
mount -o remount,rw /dev/block/mmcblk0p2 /system
busybox mkdir -m 777 /system/sd
mount -o remount,ro /dev/block/mmcblk0p2 /system
Then you can use my startubuntu script to switch from Android to Ubuntu (I mount the first ext4 partition on microSD card here, please modify this script as you like):
I mount /mnt/sdcard directory in Android to /sdcard directory in Ubuntu, and mount /system directory in Android to /android/system directory in Ubuntu, so we can easily access data in Android from Ubuntu system
I, however have following confusion.
(1) I installed Link2SD and then removed it. But this gave me permanent access to ext4 partition on my SD card which is mounted as /data/sdext2. I can read and write to that (second) ext4 partition on my SD card via any file manager which is almost 10GB and identified as mmcblk1p2. I do not need to mount it via any script as it gets mounted by default. In such scenario,
(a) Do I still need to creat a seperate directory (such as /sdcard/sd) as mount point for ubuntu partition (as it always mounts at /data/sdext2 without any extra effort) or can I skip that step?
When your guide referes to ext4 partition on SD Card as ubuntu partition, what does that exactly mean? For me whole ext4 partition is mounted as /data/sdext2 and I can access it, so how does it diffrentiate w.r.t specific ubuntu partition ...? Does it mean that I still need a directory named 'ubuntu' on it, i.e. /data/sdext2/ubuntu?
© Your guide referes to copy Lbuntu12.04 files to ubuntu partition, i.e. ext4 partition on SD Card (in my case it will be copied to /data/sdext2). While Lbuntu12.04 has multiple files with one Lbuntu.vmdk file, does it ean that your script directly mounts a VM Ware virtual image?
I am confused here as Lbuntu12.04.vmdk is neither an .img file nor an .iso file. Without any real android compatible VM Ware virtual machine running, does the startubuntu script mounts Lbuntu.vmdk VM Ware virtual image? I am missing something here so more details are much appreciated.
(d) Guide refers that other ubuntu distros/images/versions can also be used. If I put ubuntu12.04.img or ubuntu.iso file in the root of ext4 partition will startubuntu script still work? Do we still need to make an 'ubuntu' folder on ext4 partition (as whole partition is supposed to be an ubuntu partition) and than put files in that 'ubuntu' folder or do can we put all files directly into the root of ext4 partition on SD Card? (because it is by default an ubuntu ext4 partition)
(e) Does it differentiate between desktop ubuntu distros (x86 and x64 ones..32bit and 64 bits) if I were to use them as image/iso files?
Any help appreciated, please.
