There is also "ddd", though I haven't tested it on FreeBSD yet. I imagine either would be useful for st tape drives, too. It would be great if we could get either author's permission to put their program on the cpio.flp floppy. This would speed up tape installation of FreeBSD. Are others interested in this? Both program requires shared memory and semaphores. Would enabling them in the GENERIC kernel be a problem for 4MB configurations? The author of "buffer" is Lee McLoughlin (L.McLoughlin@doc.ic.ac.uk). The author of "ddd" (comp.sources.unix v15i084) is Tapani Lindgren (nispa@cs.hut.fi). Terry Lee terry@uivlsi.csl.uiuc.edu
