Allow creation of a snapshot of an empty repository

[vincentbernat]

Hi!

When trying to snapshot an empty repository, we get:

ERROR: unable to create snapshot: local repo doesn't have packages

This is easy to circumvent by creating an empty snapshot instead but it would be more convenient if aptly just created an empty snapshot in this case.

Hello,

I agree, there should be an option to allow creation of empty snapshots.
So one can create multi-component publish eg. with aptly-publisher even when there are no packages in some of the components.

+1, this should be easy to fix, this is just check in the code which should be removed

Cool, thank you for fixing this :-)

Should be available now in aptly_1.0.0+30+ga245b72 nightly
