Doing > "$2.dpkg.csv" might work but breaks the interface of how builder image scripts are supposed to work. They should only output to $2 and not assume that other files next to $2 are accessible.
Else the *.manifest.dpkg.csv will not correctly appear in the artifacts list (this will only contain *.manifest) so it may not get picked up by downstream tools.

Thanks for the input. After a closer look I moved the sbom creation to a solitary script. Does this fit better?
