[BUG] No space left on device (28)

[cooljimy84]

Towards the end of the make rpi3_64 command I get hit with this, I have plenty of disk space, just the loop back image seems full.

I can try expanding the image and running make again (not savy enough to know if it would pick up from where it was)

to 20GB, this get me to my next out of space issue.

You are using teh VFS driver on your system instead of the overlayfs.

I am currently working on building host podman/skopeo/jq tools to account for this. As a possible quickfix you could create/add the below file in the directory of your build host system

~/.config/containers/storage.conf

I'll hold off making a pull request for the image creation "homefs.ext4" size as just making it 20GB is kinda over kill (and it seems to shrink it down to the sized used after it's finished copying)
Unless you want me to test and possibly change the other build options pi4, x86 and find a size that currently works ?
