Remounting system on android emulator lasts about 10 seconds and reverses until reboot Found something odd with the Android 6.0 on x86_64 emulator (and possibly others) system images... is it something I'm doing wrong?

When I remount /system and push stuff to it, it's giving me a chance to push stuff at first but then after about 10 seconds it remounts itself automatically read only and stops me remounting it read/write, and just gives me:

# mount -orw,remount /system
mount: Read-only file system

until a reboot.

What gives? Has anyone come up against this before and solved it?

It doesn't appear to be the wrong error and I'm out of disk space - it looks OK:

/system                  1.2G   783.7M   456.2M   4096

Cheers
I saw the exact same puzzling behavior. To remedy this, use the -writable-system option when you start the Android emulator.

eg:

~/Library/Android/sdk/tools/emulator @&lt;avd_device_name&gt; -writable-system

Issuing adb remount afterward should then allow you to push to /system until you reboot or remount read-only again.
