Docker images bigger than 5GB are not supported

[PidgeyBE]

Hello

I'm trying to package a relatively large docker image with EIB.
The packaged .tar.zst file created by Hauler is 5.3 GB.

If I understand correctly, when SLE Micro starts, after it was installed, Hauler loads all airgapped images. This happens by extracting (?) every tar file to /tmp.
It seems that /tmp is limited to 4.8G, making Hauler fail:

I'm testing in a VM and results are the same for 100GB and 250GB disks.

Hauler itself mentions this in their docs: https://rancherfederal.github.io/hauler-docs/docs/known-limits

When using hauler, it will default to write temporary files to /tmp. If you do not have about 3x the amount of space available in your /tmp compared to the size of the store or the haul, then hauler may fail.

Is there any way I can make the /tmp partition larger?
Or can I make Hauler use another temp directory? They do have a --tempdir flag...
