Cache cleanups only happen if there is a cache miss, and we need to pull a new image
For quay.io/podman/machine-os, we remove all old images from the cache dir. This means we will delete any file that exists in the cache dir; this should be safe to do since the machine pull code should be the only thing touching this cache dir. OCI machine images will always have a different manifest, and won’t be updated with the same manifest, so if the version moves on, there isn’t a reason to keep the old version in the cache, it really doesn’t change.
For Fedora (WSL), we use the cache, so we go through the cache dir and remove any old cached images, on a cache miss. We also switch to using ~/.local/share/containers/podman/machine/wsl/cache as the cache dir rather than ~/.local/share/containers/podman/machine/wsl. Both these behaviors existed in v4.9, but are now added back into 5.x.
For generic files pulled from a URL or a non-default OCI image, we shouldn’t actually cache, so we delete the pulled file immediately after creating a machine image. This restores the behavior from v4.9.
For generic files from a local path, the original file will never be cleaned up
Unsure how to test, so:
[NO NEW TESTS NEEDED]

Moving from Go module v4 to v5 prepares us for public releases.
Move done using gomove [1] as with the v3 and v4 moves.

The following PR is the leading PR for refactoring podman machine with
the following goals:
* less duplication/more re-use
* common configuration file between providers
* more consistentency in how machines are handled by providers
The goal of this PR is the rough refactor. There are still rough spots
for sure, specifically around the podman socket and pipe. This
implemention is only for Linux. All other providers are still present
but will not compile or work. This is why tests for them have been
temporarily suspended.
The ready socket code is another area that needs to be smoothed over.
Right now, the ready socket code is still in QEMU. Preferably it would
be moved to a generic spot where all three approaches to readiness
socket use can be defined.
It should also be noted:
* all machine related tests pass.
* make validate for Linux passes
* Apple QEMU was largely removed
* More code pruning is possible; will become clearer when other
providers are complete.
the dir pkg/machine/p5 is not permanent. i had to seperate this from
machine initially due to circular import problems. i think when all
providers are done (or nearly done), it can be placed and named
properly.
