Hi there, something seems to be wrong with my installation, but I am not sure where to go from here on finding out how to fix it. I have my installation on an SSD showing 812GB on this partition (in gparted). I have a couple games installed. Some flatpaks. The storage on all these looks normal. Overall, my home folder shows as 230-250 GB (230 by

du

, 245 in FileLight). The rest of my system usage is weird.

`bash
sudo df -h /var
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda4       813G  681G  128G  85% /var

681G-245G is 436, so the rest of my system is taking... 400G+ of space? I found the tool [btdu](https://github.com/CyberShadow/btdu) to help scan what's taking space. So far it has scanned that

/var00/lib/containers/storage/overlay

is 366GB. It looks like maybe there is some duplication/remnants sticking around in here. There are 11 sub-folders in here that are around 9GB in size, and all contain installations for the same applications. I do my builds with

bluebuild build

locally and push the images to ghcr.

bash
rpm-ostree status
State: idle
AutomaticUpdates: stage; rpm-ostreed-automatic.timer: last run 53min ago

No pinned images sticking around. I've also tried all the subcommands/options of

rpm-ostree cleanup

and

bluebuild prune

. Is there something obviously wrong in all of this? Hoping to understand what on earth is going on here. Thanks. https://cdn.discordapp.com/attachments/1462225209565122600/1462225209930023137/image.png?ex=696d6ad8&is=696c1958&hm=ef5bbc6b189c10c34bf2013783881de19285c93d34d5294dea16c130487f90db&

You can make use of

bluebuild prune

along with

-B

for any driver you use like

podman

in your instance

I did try that at one point in the past, but I'll try it again and report back
