policy.json overwrite not honouring $XDG_CONFIG_HOME

[Luap99]

Reading the signature code I noticed that the user policy json file is always read from ~/.config and does not honour the XDG_CONFIG_HOME env var.

image/signature/policy_config.go

Line 37 in bdfde4d

var userPolicyFile = filepath.FromSlash(".config/containers/policy.json")

image/signature/policy_config.go

Line 67 in bdfde4d

userPolicyFilePath := filepath.Join(homeDir, userPolicyFile)

AFAICT the rest of our stack respects this var so I would think policy.json should do the same or am I overlooking something?

That’s reasonable in principle — except that XDG_CONFIG_HOME is, strictly speaking, a Linux-specific concept.

There was #1011 some time ago, that goes into a bit more detail.

Ah yeah didn't search for existing PRs, also looks like the same problem for registries.conf #1647

I don't have any need for this right now (juts noticed the problem while reading the code) so I leave it to you or others if they care to fix this or not.

I think I’d only want to work on this after fixing known bugs in documented functionality, but PRs would be welcome.

Either way, having this issue filed to track the improvement is valuable.
