Whenever someone describes how to install OpenMediaVault via Apt-get they use a two step process:
apt-get install openmediavault-keyring postfix
apt-get update
apt-get install openmediavault
Is there a reason that openmediavault-keyring and postfix cannot be made dependencies to openmediavault and save a step? A brief look around the web shows gnome-keyring being a dependency of gnome-core.
