No it will not. It will copy the block/character devices as files of type b & c, this will result in /tmp/RFS/dev/ being 100k or so. Doing a 'mount --bind' is, however, better than my suggestion of copying. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.
