Some users build FreeBSD as non-root in Perforce workspaces. By default, Perforce sets files read-only unless they're explicitly being edited. As a result, the -f argument must be used to cp in order to override the read-only flag when copying source files to object directories. Bare use of 'cp' should be avoided in the future. Update all current users of 'cp' in the src tree. Reviewed by: emaste MFC after: 1 week Sponsored by: Spectra Logic
