containers: large containers sometimes never start up

[troglobit]

Current Behavior

Background

Testing with multiple (quite) large containers in the same setup on a Raspberrry Pi 4B, quad-core ARM Cortex-A72, 4 GiB RAM.

Problems

Symptom 1

• Large containers hog CPU at startup/pull
• Severely affects overall boot/startup time

Symptom 2

• Sometimes the pulled image fails to load into podman
• Manually loading image works

Symptom 3

• Retries forever even if network is up
• Manually pulling image works

Expected Behavior

Regardless of their size, containers should start up unless the system is out of RAM or storage.

Observations:

• Why do images have to be pulled every time at boot?
• Why can't Infix cache the images between reboots?

Steps To Reproduce

Not at time time.

Additional information

Requiring network connection on every boot, due to the issue found in #1098, is not reason enough to wipe all images. Hence, the solution in #1098 needs to be reevaluated!
