Hi pier, I was wondering how did you manage to install system apps directly on sd-ext partition? I see when I unzip your rom that they are not in system folder. Does it have sth to do with meta inf folder which I think contains update script or there are some other files involved? I want to try that with some cm7 mod.

It's not that straightforward, but doable. I did that to accommodate big rom ~150 MB to small Pulse's /system partition (110 MB at max). I moved content of /system/app to sd-ext and symlinked it.

Updater script:
- simply copy /sd-ext content to the same named partition on sd-card,
- it also symlinks /system/app to that.

You rom should:
- be able to execute init.d scripts (cmX roms can)
- init.d script should mount /sd-ext on init
- in ramdisk /sd-ext empty folder is created to later mount to.

If rom would not be able mount /sd-ext on boot, it won't boot, as all apps are now located on sd-ext.

...init.d script should mount /sd-ext on init

I missed this part and ended in an endless boot. Thanks for the explanation. And great idea BTW.

Edit: Yep, that did the trick. Thanks again..

I thought this article was interesting: http://www.theregist...04/02/sony_ics/

Is this people's experience with CM9? Does it run quite slow on our minimal hardware?

Excerpt:

"Sony says its customers should avoid upgrading their Android devices to Ice Cream Sandwich, adding that many of them won't get the option anyway.In a blog posting on Sony's Developer World the company explains why the latest version of Google's mobile OS uses a lot more memory and is slower than its predecessor, not to mention being less stable on underpowered kit. Sony leaves it up to customers to decide if the bling-laden interface is worthwhile."

Rightly described memory issues in the article. Not only ICS, but even gingerbread tends to kill launcher often. So when returning from memory consuming app, you end up on empty screen with only a wallpaper, and only then launcher is starting. On Pulse at least.
Never a case on 512 MB device.

EDIT:
from the referenced Sony blog:
"ICS was developed with Galaxy Nexus in mind, which is based on a TI platform with dual-core processor and 1GB RAM."
and then:
"We are now adapting ICS to run on our 2011 Xperia™ smartphones, which are all built on a Qualcomm platform with single core and 512 MB RAM. "

I dropped into a HTC showcase store last night to drool over the latest hardware. Wow, phones running Gingerbread where everything is instant and nothing ever lags. Yes, I do want one! B)

I know there is only so much one can do with our limited processor and memory, but it's amazing how far the weak hardware can be pushed.

"Android 4.0 Compatibility Definition" document:

"7. Hardware Compatibility
7.6. Memory and Storage

7.6.1. Minimum Memory and Storage
Device implementations MUST have at least 340MB of memory available to the kernel and userspace. The 340MB MUST be in addition to any memory dedicated to hardware components such as radio, video, and so on that is not under the kernel's control."

In translation it mandates 512 MB of RAM for ICS, as not only Android is using the memory.
Also OpenGL 2.0 is a requirement according to the doc.


EDIT:
8. Performance Compatibility
The following applications should
launch within the specified time.
Browser:  less than 1300ms
Contacts: less than 700ms
Settings: less than 700ms
