Progress update and INT2SD implementation request form!
With holidays starting, and more free time on my hands, I've decided to revive this project. Having my hard drive fail on me recently, and losing the request log, it has become obvious that I need a new system of handling requests, and it is here. If you have requested a ROM before, please send a request again, via this form.
Please submit all further requests via this form!

INT2SD thread for Sense ROMs

This is INT2SD, a new method of achieving D2EXT. It is meant for developers who wish to implement this functionality in their ROMs, since, due to the nature of the method, there is no way of making a flashable .zip which would be universal and work on most ROMs (yet?).
What differs this method from the old ways is that it uses no symlinks whatsoever.
INT2SD mounts an SD ext partition directly to /data, and this requires making changes to the boot.img, hence why universal flashable zips are not an option. The real userdata partition is mounted on /realdata and used for the e2fsck log.
Sorry for the link downtime, there were some critical bugs which I did not have time to fix. Therefore I took my time and added symlink checks, fixed fsck and more.
INT2SD-S - "Speed" (default as of 29th Jun)
Main characteristics:
The new "speed" flavour mounts ext to /data and userdata to /data/data, achieving great speed while still retaining excellent storage capabilities. It's used with the CM7r2 HBOOT. This is now the default flavour, offering great speed while still being able to hold a hefty amount of apps.
INT2SD-M - "Mass" (discontinued)
Main characteristics:
The classic "mass" flavour mounts ext to /data, thus eliminating the need for the mtd5 userdata partition. It has proven to be slow even on some of the faster cards. Due to INT2SD-S being able to hold a very high number of applications, and still being much faster, this flavour is discontinued.

Cross-device implementations
For now, no. You may submit requests, but I won't be able to fulfill them for a while. I have quite a lot of real life work on my plate, not to mention a list of Desire ROMs I have to tend to. After that's done, I'll be happy to try blind-porting it to whichever device you wish, but my priority are Desire ROMs, primarily because it's a lot easier to implement INT2SD into ROMs for a phone I already have.
Universal update zips
Also, no. Each ROM is different, and due to the nature of INT2SD, it is simply not possible to make a one-for-all universal update zip. Every ROM requires tending to its peculiarities, especially Sense ROMs, and I would rather not take the change of trying to make one and end up with a flashable bootloop zip.
Why don't you just publish instructions on how to implement INT2SD for devs to use?
Instructions:
Pick your ROM featuring INT2SD, download it and flash it. You only need 1 ext2/3/4 partition. Due to /data/data being on the SD, a high-class card is recommended. Due to Gingerbread AOSP ROMs generally being pretty small, there's still quite a lot of unused space left on /realdata, to which I plan symlinking the /data/data directory so that INT2SD plays nice with lower-class cards too.
Remember to flash Google Apps, available here, if you opt for CyanogenMod.
All zips are signed for your convenience.
Flashing other kernels on top of these ROMs should work, though it hasn't been tested. If you try it, please let me know how it went.
EDIT: Seems there are people spreading false information on how this should be installed due to their own misunderstanding of my post. While I thought the instructions are simple enough, it seems they are too simple and do not describe the process. So, let me clear this up once and for all:
THE ROMS HERE ARE FULL ROMS THAT ALREADY HAVE INT2SD IN THEM.
THESE ARE NOT ADD-ON ZIPS.
Meaning, if you wish to use CM7 with INT2SD, just download CM7 from here. It is actually full CM7, along with INT2SD. So, the process is as follows:

Current bugs:
-
Credits (alphabetically):
Alex-V - providing me with the first Sense ROM to implement INT2SD in
brabo, GShellz admin - huge help with bash scripts implemented in the ROMs
CM - a base ROM for implementing the method in
Droidzone - suggestions, help with HBOOTs
Hacre - massive assistance as well, kicking me to try and realise the main idea and for coming up with names "INT2SD" and "fatsys"
JieeHD - help with compiling/decompiling the boot.img files and his excellent guides on FYA
Pulser_g2 - massive assistance, ideas on the reboot bug and hosting
Richard Trip - making GingerVillain which now has a version featuring INT2SD
snq- - pointing out a huge typo and saving me multiple hours of pointless work
ubuntubhoy - a kick in the arse I needed
... and everyone else in the #villainrom IRC channel for help and mental support! Thank you all, and everyone I forgot to mention (PM!).
Disclamer: I'm not responsible if something goes wrong and wreaks havoc upon you, your phone, your card, any part of your phone, your friends, your family, your close or distant relatives and/or your pet, but I will gladly provide assistance if it does.

INT2SD-S - "Speed" (default as of 29th Jun)
Main characteristics:
- /data on SD ext, /data/data on internal
- /data/data limited to 280 MB (probably enough for more than 100 user apps)
- noticeably faster on slower cards
- for use with CM7r2 HBOOT
The new "speed" flavour mounts ext to /data and userdata to /data/data, achieving great speed while still retaining excellent storage capabilities. It's used with the CM7r2 HBOOT. This is now the default flavour, offering great speed while still being able to hold a hefty amount of apps.
INT2SD-M - "Mass" (discontinued)
Main characteristics:
- /data on SD ext
- number of apps is only limited by ext size
- requires a faster card
- for use with fatsys HBOOT
The classic "mass" flavour mounts ext to /data, thus eliminating the need for the mtd5 userdata partition. It has proven to be slow even on some of the faster cards. Due to INT2SD-S being able to hold a very high number of applications, and still being much faster, this flavour is discontinued.
