Android's file structure is so incomprehensible. I'm genuinely surprised there hasn't been any significant effort made to make it more readable. Pictures saved in app directories, downloads, camera, images, pictures, media, DCIM???.

Open source developer and Linux enthusiast here. Although cluttered, Android's home directory is fairly simple to understand

The nightmare begins when you take a look at the root filesystem.

One time I was trying to port an OS to my phone and I had to figure out the Android init system. Went to source.android.com and what. the. fuck. Just as a side-by-side comparison:

Linux boot sequence: Android boot sequence (unmodded, SIMPLE):

There are so many wrong things about it like why are there 11, 12 places to put programs (/system/bin, /bin, /usr/bin /system/usr/bin, /sbin, /system/usr/share/bin...)

Why the fuck drivers are scattered around folders instead of just /lib/modules

Why is the home directory /storage/emulated/0/ instead of just /home/0/ (also why the user is named "0")

Where the fuck is everything???

God (Linus Torvalds) forgive me but even Windows is better than that shit

i wonder if that graphic is up to date with system as root and A/B dynamic partitioning and whatever crazy new bullshit google invents with every release

I raise you all of these monstrosities:

Phones launching with Android 13 without a dedicated partition for recovery mode

Phones launching with Android 13 without a dedicated partition for recovery mode

Phones launching with Android 13 with two dedicated partitions for recovery mode (two because of A/B partitioning scheme)

Phones launching with Android 13 with a two dedicated partitions for recovery mode

Phones launching with Android 13 with one dedicated partition for recovery mode (only one because A/B partitioning scheme is not used)

Phones launching with Android 13 with one dedicated partition for recovery mode

Phones that launch with or upgrade to Android 12, that use a generic kernel image, without a dedicated partition for recovery mode

Phones that launch with or upgrade to Android 12, that use a generic kernel image, without a dedicated partition for recovery mode

Phones that launch with or upgrade to Android 12, that use a generic kernel image, with two dedicated partitions for recovery mode (A/B partitioning scheme)

Phones that launch with or upgrade to Android 12, that use a generic kernel image, with two dedicated partitions for recovery mode

Phones that launch with or upgrade to Android 12, that use a generic kernel image, with one dedicated partition for recovery mode (non-A/B partitioning scheme)

Phones that launch with or upgrade to Android 12, that use a generic kernel image, with one dedicated partition for recovery mode

Phones that upgrade to Android 12, that does not use a generic kernel image, with no dedicated partition for recovery mode

Phones that launch with or upgrade to Android 12, that does not use a generic kernel image, with no dedicated partition for recovery mode

Phones that upgrade to Android 12, that does not use a generic kernel image, with dedicated partition(s) for recovery mode

Phones that upgrade to Android 12, that does not use a generic kernel image, with dedicated partition(s) for recovery mode

In Android's defense however, a phone would likely use only one of these layouts at a time. The question of which of these layouts does a said phone uses though, that's a more complicated question.

That's not correct though. The GNU+Linux version is missing the bootloader and initramfs.

The Linux boot sequence link doesn't work for me

Init

Linux Kernel

It's a graph, showing a red oval with the text "Linux Kernel", an arrow points from the red oval to a light-green oval titled "Init".

"Linux Kernel" --→ "Init"
