Mount /system on Android 10 with Magisk

I am using Magisk 20.4 and trying to mount /system on a Google Pixel (1st gen) running Android 10. I have tried using: adb shell su -c mount -o rw,remount /system that gives: > mount: '/system' not in /proc/mounts The following also do not work: adb shell su -c mount -o rw,remount / > '/dev/root' is read-only adb shell su -c mount -o rw,remount /sbin/.magisk/mirror/system_root > '/sbin/.magisk/block/system_root' is read-only I was also curious whether stuff in /sbin/.magisk/rootdir/system/ can actually override stuff in /system/ but that doesn't seem to be the case.. Has anyone managed to mount /system on Android 10? Is this issue specific to Google Pixel? Cheers, Paschalis #### Trying Hack5 suggestion gives me: > mount: '/system' not in /proc/mounts Since I knew that /sbin/.magisk/mirror/system_root was a valid mount point, Ive tried the following, which still fails: mount -wo remount /dev/block/bootdevice/by-name/system$(getprop ro.boot.slot_suffix) /sbin/.magisk/block/system_root > mount: '/sbin/.magisk/block/system_root' not in /proc/mounts # UPDATE: Turns out it's impossible to mount /system on a factory image of Google Pixel. But, I was missing the whole point of Magisk! So I made a few modules and I can override/add the system libs and bins that I need. There is even support for apex on Android 10!
