[DEV] [MOD] Repartitioning

[USBhost]

http://forum.xda-developers.com/showthread.php?t=1388996
Has anyone thought of doing this?


Edit: compiling parted is harder then i thought !!

I will work on getting parted built for our Nexus 9
Because Parted 1.8.8.1.179-aef3 does not work on our Nexus 9

Note: will update this thread with a lot more info
When I get it working.

Note: if I got it built
I will test this on my Nexus 7 first. if everything goes well
Then I will do this on my Nexus 9

I think in nexus 9 , repartitioning is not required as apps are installed in internal storage and no limit is there.. :what:

Well I was thinking of making
system smaller by 1g
and making data bigger by 1g

Yes! This is exactly what I was looking for!
I commented about this somewhere I remember. Seems like I have way more space in my system than I need.

Lets hope that in can compile it

There is even more utility for purpose of dualbooting a more conventional linux distro.
I.e., add a menu-driven multi-boot bootloader to the start of the boot partition, allow to select either a conventional android boot, or a <pick your favorite linux flavor> boot, which of course, loads a different kernel, and a different base filesystem. It is conceivable to share the userdata partition, i.e. /data/media for regular linux userdata and sharing data between android and another distro, but it would be helpful to set a couple of GB aside for the system data.

This approach requires you to be S-OFF & modify your bootloader - this also requires a modified kernel.
I have been using another less invasive approach successfully since ~3 years (even posted about it somewhere on xda); I'm basically using the system partitions (userdata, cache, system) as separate LVM volumes.
You can even have encryption!
You just need a LVM binary (and cryptsetup if you need encryption - automatic decrypting if you have the key as OTG) and a slightly modified boot.img (along with the recovery if you want to avoid manual work):
Obviously, you need to modify the fstab to point to the /dev/mapper paths as well as the LVM initialising part as service at the top of your init.rc

This this a nexus
So S-OFF is not needed

And I don't think you need to modify the bootloader


P.S.
Can any one help me compile parted
So far no luck

1: you could use the fdisk builtin busybox binaries
2: you could use sgdisk instead fdisk/sgdisk. There are even some on xda: http://forum.xda-developers.com/showthread.php?t=1605535
3: here are some busybox (along with a variant compiled against glibc instead of bionic), LVM, & cryptsetup binaries: https://drive.google.com/file/d/0B8rpJsF4EG0Yb2FWT3liOTRucnM

Any progress with this? That 2.5GB System partition is overkill. Would definitely transfer 1GB of that to my Data partition.
