It is basically a change from kernel 4.18 - 4.19 - metacopy is set to yes in archlinux kernels (/sys/module/overlay/parameters/metacopy) and overlayfs should override this which it does not at the moment.
My original thread on the archlinux forum:
There is a patch for the 4.19 kernel line for enabling overriding of metacopy by overlayfs:

A workaround for now is to disable metacopy:
Code: Select all
echo N | sudo tee /sys/module/overlay/parameters/metacopy
