I don't think there is a boot.img for that, it may be used via chroot though. Good luck on that!

EDIT:

Since you always replace the same values (ie. yaffs2 to ext4, a specific nand partition to a specific sd partition) what about creating a patcher, that way you wouldn't need to create a separate boot.img for every single rom.

You mean like an sh script that will unyaffs, change values, thencreate the ext img?

And what about s2e with this mod, can i just create another ext3 partition ?

Yeah ..
how would s2e accept one from two partitions

None, windows file systems can't handle linux style symbolic links.

I've posted a user friendly boot.img kitchen for linux that's just perfect for this use. I'm sure you can use a ubuntu live-cd or similar.

Use virtual box, I use it to compile ROMs on.

Added tool for modifying boot.img

[XMasterNinni]

@android@sam
If you release the source of the tool, I could join the project and I can help you a little with that.

Most (all?) mount scripts for S2E use /dev/block/mmcblk0p2 so that is the second primary partition on the SD-card.

You can, of course, just change that in the mount script is you want to use another partition. You can have a maximum number of four primary partitions.

I haven't looked at the scripts yet but i'm going to assume it mounts /system to /dev/block/mmcblk0p2 so the easiest way to use S2E would be to make four partitions (fat32 - ext3 for second rom - ext3 for second data and ext3 for S2E) and change the mount script in init.d to mount /sd-ext to /dev/block/mmcblk0p4

Download and unzip the tool to any directory.Here i will consider for the cygwin users, say c:\modify-boot.
Now,open the terminal or cygwin bash shell(for windows users) and mount the directory by typing:
​   cd c:\modify-boot    and press enter.
...

Have you actually tested this that it works with cygwin? If you split boot.img and pack it back together without any modifications, bytesize of the new boot.img is different from the original image. From what I've read, it's because windows file system breaks symbolic links.

Now the tool will tell you to copy init.rc file.So copy the the correct version of init.rc (i have labelled them) to the /bootimg_(some nos will be here)/boot.img-ramdisk folder.Don't for forget to rename it to init before copying it!!

init.rc is not some blob that you can just copy from one ROM to another. I would highly oppose if someone was to use to that init.rc in Swedish Snow. init.rc is also different in CM7 and ZTE stock based ROMs.

Because it's matter of editing only few lines, you'll probably be able to change them using sed. This would also make it possible to automate the whole splitting/modding/packing process.

Avast is giving me a virus warning on the file mkbootfs.exe and moves it to quarantine.

Virus is win32:Kukacka.

Doesn't matter much to me since i won't be using windows for the actual procedure but it's something that you should remove ASAP.

Check the size of your boot.img.Have it been successfully unziped from the rom?

I was successful in installing both nand and SD-Roms but i had to change the updater script for CM10, you're missing a line to set permissions for su and since i'm using RA recovery i had to change the mount and format lines.

I also changed the nand rom's init scripts so that it will mount sd-ext to the fourth partition and finally i changed the RA recovery so that it understands that the fourth partition is SD-Ext when making backups/restoring backups.

Since most people don't use RA (but i kinda have to because it's the only recovery that actually works with ext4 and my gen3 device) i won't post it here without request.
