Defining the partition structure

Let’s immediately classify what we will discuss next. This will help avoid misunderstandings and ambiguities in the future discussion.

Let’s forget about A-only, A/B, and SAR for a second. Well, it is not possible to divide existing partition structures in this way and not get completely confused. Not now.

“Real” A-only-everything is normal and clear, as on Android Kit-Kat. The system is a familiar to most, /system .build.prop is located right in it - /system/build.prop. All the usual directories, files, and patterns. The base and initial appearance of the Android OS. A/B firmware system are not suitable.

“Real” A/B-partition structure (remember) is intended for updating “on the fly” and “lossless”. This implies that there are two system partitions in the device’s drive - /system_a and /system_ b , respectively. Why is that? While you are sorting through photos in one of your favorite social networks, watching a movie, reading, etc. in a system loaded with, for example, /system_a - “Google” (or a case-not the point) it is already downloading and possibly installing the update on Your device in the /system_b section. Then switches the boot slot in the loader from /system_a to /system_b. When you reboot, you see an updated system loaded from the second slot, genius, right? Plus, if the update did not get up or got up inappropriately - it does not matter! Switch to the pre-existing slot and there is no problem. Well! The feature of this partition structure is the directory structure, in which the usual user content of the /system directory (build.prop, media, priv-app) has become a level deeper - /system/system. System - this is now /system/system. build.prop is located in - /system/system/build.prop. All the usual directories, files, and patterns are already applied to /system/system. Here I want to highlight three main points:

  1. Because of this, it became a bad fashion to call the directory structure a partition structure.
  2. Firmware still signs (and will!) A/B, not because they are for phones with /system_a and /system_b, but because the directory structure is similar to that of A/B phones.
  3. A/B firmware fit.

“Not Real” A-only or A/B-SAR (system as root). What do we have? Doesn’t make any sense! The partition structure is A-only, the directory structure is the same as A/B:

  1. The System is located in a subdirectory (like A/B), but it doesn’t have to be /system/system , it can also be /system_root/system.
  2. It can occur both on phones with “Real” A/B, and on other smartphones.
  3. A/B firmware fit.
  4. Structure sections A-only.
  5. Build.prop in /system/system/build.prop or in /system_root/system/build.prop.

In other (even simpler) words:
System or /system, or /“something”/ system. At the time of writing, the option to determine which firmware to install, I will offer:

  1. A/B if the root of the system partition contains the init.rc file and does not contain the build.prop
    file.
  2. A-only if the root of the system partition does not contain the init.rc file and contains the build.prop file.

Attention!

Look NOT from under the running OS, but through TWRP or in a disassembled image of the system partition, over which GSI will be flashed.

Can you provide some links to your sources? I built /e/ v1-q a couple of days ago for sargo (pixel3a). It uses A/B (but is not a GSI). Here’s how things look like, looks to me like what you call “All the usual directories, files, and patterns. The base and initial appearance of the Android OS.” :

adb⏎
~/M/o/P/apps> adb shell
sargo:/ # cd /system
sargo:/system # ls

I’m not an Android whiz, I’m learning, I’m just asking for clarification here. The only thing that I believe is different here from the “original Android” is that vendor and product are partitions. That’s treble stuff IIUC and enables GSIs.

Have you ever searched the web for GSI ion your device? You will find posts like this

And I think your question should be placed on xda to phhusson, the master of GSI

11

Why would I look for stuff on how to install a GSI on my pixel3a? My post didn’t ask about that in any way. I’ve installed GSI successfully on my phone, including yours, as you know.

Why would I post on xda when I’m responding to a post here? Gorets posted a bunch of information and I’m looking at my device and seeing something different from what he stated (at least it seems different to me), and so I’m asking for clarification and where his information comes from so I can trace back to where the discrepancy comes from.

12

Ah OK, than I have misunderstood your post. Sorry. I have it understand that way, that your GSI wasn’t working and you want know how to fix. That’s why I have answered the way I have done.

But anyway, all questions about how GSI/treble is working and what is need, the best guy is PHH on XDA

Hi,

about the source, it’s Russian forum (4pda). This is a translation into a clear language from the general topic, who is too lazy to read the entire header and the first 20 pages of the topic. Source - people who wrote about it earlier in the topic + view of the situation.

If there are any specific questions, it is better to search for them online, and if you can point out what should be corrected, then I will be very happy to make adjustments

14

@Gorets, thanks for the clarification. I’m not in a position to offer corrections, but as I stated and showed in my previous post my A/B device has a “normal/simple” /system root. It does not have /system/system nor does it have /system_root/system. Build props are simply /system/build.prop. So maybe there’s a translation issue somewhere and A/B phones can have a different filesystem root structure but they don’t have to.

15

I just noticed that you’re looking out from under the system) my message included this:

Look NOT from under the running OS, but through TWRP or in a disassembled image of the system partition, over which GSI will be flashed.

Is it possible to disassemble the firmware or look at the file system from under twrp?

16

@Gorets is right. Boot in TWRP, mount /system and you will find the /system/sytem

17

Yes & no, I did some more digging, starting with unpacking the payload.bin for my pixel3a build… What I see:

  • the filesystem image for the system partition is SAR (system as root), which means that that filesystem gets mounted onto / and thus contains a /system subdirectory. I gather that on the old days the system partition used to be mounted as /system.
  • thus on a running system /system/build.prop is where it needs to be.

Where I believe the confusion comes about is when talking about TWRP. I cannot run TWRP on my device, it doesn’t support it, so I can’t check it out for myself. However, in the latest TWRP changelog I see: “system_root bind mount to /system - Chaosmaster” so I think that what’s going on is that TWRP has a standard mount point for the system partition and when it mounts the partition there it doesn’t look as usual because it’s SAR.

So what’s confusing or what changed is not what one sees on a normally booted device but what one see on a device booted in TWRP recovery. And it seems that TWRP is trying to fix/hide that using bind-mounts. The impact is that when loading patches/hacks via TWRP files may not be in the place they used to be…

Have you flashed tge vbmeta.img? Have you FORMAT data (not only wipe)?
Have you wiped system, davlik, cache?
Have you used the right layout?

And dumb question: have you unpacked to xz file or only removed the xz?

On Xiaomi it MUST boot. I’m using it on 3 different Xiaomi devices.

Have you tried any other AOSP GSI?

21

You are meaning the recent button ? That’s I have heard on other users to. Have you tried to set it up in Settings/buttons ? Or is this option greyed ?

I’m you building a new set. Hope the issue will solved on all devices.

22

could you try the mini version ? It’s some days older and could be that there the sources where better
