Understanding Disk Space Usage in /overlay

Hey everyone! I’ve been trying to figure out why my system is running low on disk space, specifically in the /overlay partition. I’ve noticed that it’s only a few megabytes short of what’s needed for an upgrade, but I want to make sure I understand what’s taking up all that space. I ran a quick du -s * | sort -n in the /overlay directory and found some interesting numbers. The /etc folder seems to be the main culprit, with a lot of files inside /cmh-ludl. These files have extensions like .lzo and .lzoenc, which I assume are compressed. I’m curious if these files are necessary or if they can be safely removed to free up space. Has anyone else dealt with similar issues or have insights into what these files are used for? I’d love to hear any tips or tricks you might have for managing disk space in this context. Thanks in advance for your help!
