SyncFirst = package ...
           Instructs pacman to check for newer version of these packages
           before any sync operation. The user will have the choice to either
           cancel the current operation and upgrade these packages first or go
           on with the current operation. This option is typically used with
           the pacman package.  NOTE: when a SyncFirst transaction takes
           place, no command line flags (e.g.  --force) are honored. If this
           is not ideal, disabling SyncFirst and performing a manual sync of
           the involved packages may be required.
