Overlay Filestsystem doesn’t seem to work anymore

Since a few days the overlay file system doesn’t work when I install it via raspi-config. After the reboot, the default file system loads, and changes I make are persistent.

Linux pi-paper-1 6.6.51+rpt-rpi-v7 #1 SMP Raspbian 1:6.6.51-1+rpt3 (2024-10-08) armv7l

This is the 32bit version, headless, on a raspberry pi 3a+. I’ve had the same issue on another 3a+. I haven’t tested another pi yet.

Checked it a bit more.

• Did a fresh install of Raspberry Pi OS Lite 32-bit with Raspberry Pi OS imager
• No updates, no upgrades, right away raspi-config -> enable overlayfs
• The overlayfs does not work on Raspberry pi 3a.

When you do a fresh install and first apt update and apt upgrade it works. So there’s no real issue with rpi 3a.

I tried it on a Raspberry Pi 4b as well. Here there’s clearly a bug:

• Did a fresh install of Raspberry Pi OS Lite 32-bit with Raspberry Pi OS imager
• Did all updates and upgrades
• raspi-config -> overlayfs doesn’t work at all. Tried it many times.

Tried it again with a fresh install of Raspberry Pi OS Lite 64-bit, and here the overlayfs works. So it’s an issue with the 32-bit rpi 4b combination. Not sure if this is the right place. If you know where I should post this, I’ll gladly do so.

Hi, I also get this issue on the Raspberry PI CM 5. Clean install of bookworm, first thing I do is to set overlay and read only memory, and then reboot. All the changes, new files etc. are persistent :(
