This occurs because swapon is called twice, first in S10checkroot.sh, then in S35mountall.sh. Ideally I guess some smarts to detect swap files that are now available but have not yet been activated, rather than simply trying to remount all swap filesystems a second time would be helpful, as this error message has the ability to unnerve the unwary.
