Magisk does not work on PineNote

[DorianRudolph]

I'm trying to root the PineNote, which I am aware is an odd device.
I use the method of patching the boot.img

Install log:
magisk_install_log_2021-12-26T21_27_19Z.log

The Magisk app does not detect the installed magisk.
Running su or magisk --daemon both result in the output No daemon is currently running!.

Boot log from UART:
boot.log

Below are the parts that seemed relevant to me.

Regarding, [ 2.666118] EXT4-fs (mmcblk2p16): VFS: Can't find ext4 filesystem, I think the userdata partition is in f2fs format.

Device: PineNote

Magisk version name: 92546e8
Magisk version code: 23016

[canyie]

userdata partition is in f2fs format

this is expected, and Magisk can handle this case properly.
You problem is, magiskd gets killed by init:

[DorianRudolph]

Thanks. What is the first wrong line in the log? Should pGl3f9lRb not exit or is the issue that its children are killed? The killing of children behaviour exists since 2019, so that should not be the issue? 残页 ***@***.***> schrieb am Mo. 27. Dez. 2021 um 01:58:

magiskd should escape from current cgroup to prevent itself from being killed. May you upload /proc/mounts?

[DorianRudolph]

Here is /proc/mounts
mounts.txt

Just for fun, I also tried Magisk 22 and 22.1, both of which did work even less because they did not even install the su file and took significantly longer to even boot. Log file:
boot_22.log

[canyie]

looks like a normal cgroup v2 mount structure... please test this build: https://github.com/canyie/Magisk/actions/runs/1627522914
If it still doesn't work, please open /etc/cgroups.json, check every key named Path, open them in file explorer, and check if it has some subfolder named in "uid_" format (like "uid_0" "uid_1000").

EDIT: Download link updated since github action broken.

[DorianRudolph]

Thanks a lot, this seems to work now!
