Description of problem:

During UPI network install on UPI cluster, the installation fails consistently on RHCOS 4.20.11 and 4.20.13 when node-image-pull.service attempts to import the release image via ostree.

Journal shows:
Importing regfile: min-free-space-percent '3%' would be exceeded Filesystem:
tmpfs /var/ostree-container ~4GB, ~96% used Increasing tmpfs size allows the install to complete successfully.

How reproducible:

100% on:4.20.11 4.20.13
Not reproducible on:4.20.0

Steps to Reproduce:

Behavior does not reproduce on RHCOS 4.20.0.

This suggests a regression in: RHCOS live environment tmpfs sizing, payload size assumptions or ostree import behavior.

Actual results:

New clusters cannot be installed using latest 4.20.z images unless:

tmpfs manually resized, OR
images pinned to 4.20.0

Expected results:

It should include without manual intervention
