[Q] DualRomX2 = 4 roms work on defy?

---

I wonder if this work on defy.....

http://forum.xda-developers.com/show....php?t=1100777

If someone try this...plase let me know

I don't think so

would be great....

I didn't tried it but theoretically it should work. Maybe the scripts must be adapted.
How does it technically work? Maybe via chroot or does it use something like our 2ndinit-bootmenu vor booting these images?

Relly?
Relly?

Second boot in bootmenu could be used for that.. but requieres a vesrsion of android modded to work on sdcard...

main settings are in init.rc files and it should be possible to mount /system and /data from sdcard partitions.

The problems will be related to usb motoportal and mass storage which unmount sdcard

I think this can be solved by partitioning the sdcard into two partitions, one ext3 for storing system and data images to boot from it and other fat for the user files, so that mass storage will unmount only the second one!

How do they do on the original project, though? There should had been the same problem also...

Running the system from sdcard I think can be a little slow, but it may still usable... Only testing for knowing...

I created 2 partitions o my sdcard.

1) EXT3 2GB
2) FAT32 6GB

Then I installed gentoo on ext3 partition.

I can chroot into ext3 partition and use all gentoo (linux) commands. I installed Apache, squid, etc and it worked fine. I can run a WEB server on my Defy

And I can access the FAT32 partition on my PC even with the ext3 partition mounted.

Hi Dedraks!

It's basically the same idea I gave, you have two separated partitions and so one can be mounted and unmounted independently of the other. But in the original project linked above the rom images are inside the sdcard's user partition, that's the same that's unmounted when the phone is connected to computer. I've asked how they did to get around this issue at the project thread, but I'm starting to think that if you want to access your sdcard from the computer using the phone you'd need to boot the rom inside nand and not sdcard, at least the way they did it...

As I don't have my Defy at the moment would you mind posting the content of the init.rc file (it's placed inside rootfs methinks) so that we can take a look at it to see what can be done?

Thanks!
