I'm not parsing much of this.

Suggested change
When CONTAINER_HOST environment variable is set default to true.
When true, access to the Podman service will be remote. When the CONTAINER_HOST environment variable is set, the remote option defaults to true. Remote connections use the local containers.conf file by default.

Is remote false by default or set from containers.conf? That should be added.

Users enabling CONTAINER_HOST==PATH is indicating to podman they intend
to use remote functionality.

Fixes: containers#11196

Update man pages to document all of the environment variables.

I do not think this works. Remote must be parsed before any cli commands are defined. The code handles this in a special way here:

func IsRemote() bool {

This is because the cli changes depending if we are remote or not, so when cobra parsed the --remote flag it is already to late.

Current code does not check early enough.
