Not on this phone, it's been discussed several time's in the past with no successful solution's.:)

I know this is true, but if you think about it... why not? In theory it should be no big deal to shrink /system into a small boot loader partition which calls one of a group of other partitions containing different ROMs. Sounds simple enough, if you think about it... :)
 
When you put it that way it doesn't sound much different from partitioning and dual-booting on Windows... I can see so many benefits to dual-booting on Android :D

Exactly! The principle is the same, and shouldn't be that hard or someone who knows the Lindroid environment a little better than I.
 
I imagine that you could rewrite the RAM disk in the boot image to allow for choosing different ROMs at boot.
 
Haven't even explored this. I forked a method on my github a long time ago if anyone wants to take a look, but backup and restore is easier on our end.
 
There's an app called switch me on the app store, it basically copies your system and let's you log in and out at will, maybe you could look into that. If you look back about 10 comments the developer states it flashes your ROM, and rebuilds caches, etc.

I believe what this does is merely swap out parts of the ROM, e.g. your app and data folders. I surmise everything it does has to be on the same ROM, and if it worked directly with the partitions themselves, it almost certainly could only work on a specific phone or family of phones since the manufacturers all map their partitions differently.
 
All we really would need is a script or binary which could be used from within CWM or TWRP which would swap out the contents of /system and exchange them for another.

If someone knew Lindroid really well, a binary could be made which could be called from sysinit (or perhaps a little before, depending on the boot process) which would do the job from within Android, with the obvious benefits of having a GUI.

Sounds easy enough lol
 
this is probably far fetched but... couldnt someone make a script that updates the hardware to make it recognize 2 /systems? without having to go through cwm or twrp and make a custom bootloader. like i said its far fetched, but is it possible?

Most definitely it's possible, I'm just not sure how much effort it would take. At least we'd have the benefit of having existing Linux-based multiboot software such as Grub off of which to base such a thing.
 
Theres the space issue of having two roms on one phone which I guess could be solved by moving to partitions on the SD card. Could more than one partition be made so they could hold one rom each like in Windows where you can boot from multiple partitions on the same hard drive?
 
When you wipe the system in twrp, and flash a new a Rom, does it delete actual /system folder, or rather delete contents inside the folder?
 
Would it be possible to make the phone boot from the OS on an SD Card? of course after this is made (hopefully) all the devs would have to find a way to incorporate this into their roms right? also if we could get the hardware to recognize a partition of the SD Card as /system etc. we would be able to do it right?
 
I believe that requires a custom bootloader... And unless we receive an endless supply of warps to brick... Not gonna happen anytime soon

Perhaps we could remount /system so that it symlinks to /sdcard or something? Just a thought.
 
How complicated would it be to make a script that would move the contents of /system to a clone folder of a different name, leaving the system folder open for another Rom?
