Required Ports at Package Build Time?

[Thomas Amberg]

Hi,

the Snappy package format allows services to specify required ports at package build time.

(see e.g. https://wiki.ubuntu.com/SecurityTeam/Specifications/SnappyConfinement)

How does this compose? E.g. if I install Snappy apps from different vendors?

Is there an alternative mechanism to specify ports per "deployment"?

Kind regards,
Thomas
