[BUG] HAOS on Pi 3 Not Cleaning Up Docker Overlay

[smashedr]

Describe the issue you are experiencing

After using Home Assistant for over 1+ year, the disk space was consistently increasing. I assumed it was data being collected; however, after debugging the issue I realized the DB was only 200 MB and InfluxDB only had 1GB of data. Yet my 32 GB disk was full. So I mounted the disk onto a Linux system to see what was using all the disk space.

0 root@kubuntu22 [/mnt/docker]$ du -sh * | sort -rh
20G	overlay2

Every time I updated, it consumed more disk space, and never reduced until it filled up with 20GB of data in overlay. The only solution was to re-install HAOS and restore from backup. I am now down to 15% disk usage from 90%.

I assume in 1 more year I will have to do the same thing. Is this by design, or is this a bug?

What operating system image do you use?

rpi3-64 (Raspberry Pi 3 64-bit OS)

What version of Home Assistant Operating System is installed?

6.6.28-haos-raspi

Did the problem occur after upgrading the Operating System?

Yes

Hardware details
