Update module and overlayfs file systems

We are using mender to deploy our software on raspberry pi systems.
Our system is using overlayfs
When using file update module, the pushed file is copied but on the “in memory” file system.
So, after a reboot, the file disapear.
Is there any solution to patch the system permanetly in theses conditions ?
Thanks for help

I don’t know of a way to do that but I’m not terribly familiar with overlayfs. I’ve only ever used it to ensure that any changes are lost on reboot. You may want to consider putting the new files into the /data partition instead.

I repush this topic as we haven’t found a solution yet. Any insight ?
