docker.Untar (https://github.com/mudler/luet/blob/master/vendor/github.com/docker/docker/pkg/archive/archive.go#L942) requires absolute paths. We didn't do any input validation before, assuming the path passed by were absolute since they were coming from YAML configuration files, now that this is not the truth anymore we need to sanitize the input. With this change we check if the given path is absolute or relative, if it's relative we calculate the absolute path and use it in place.

"luet database create" injects a package in the system database without actually installing it, use it with caution.
|
|
|
|
This commands takes multiple yaml input file representing package artifacts, that are usually generated while building packages.
|
|
|
|
The yaml must contain the package definition, and the file list at least.
|
|
|
|
For reference, inspect a "metadata.yaml" file generated while running "luet build"`,
