Install Subpackages Without Creating Snapshots

Hi,

when installing a package with the parameter extractOnly=true (e.g. curl -u admin:admin -F cmd=install http://localhost:4502/crx/packmgr/service/.json/etc/packages/mypackage.zip?extractOnly=true) it is possible to install a package without creating a snapshot before the package gets installed.

But if this package contains subpackages then still snapshots for all those subpackages are created. Is there a way to avoid creating a snapshot for subpackages, too?

regards
