I tend to agree. For some time, FreeBSD has been heading away from requiring users to re-compile the kernel. If ATAPICAM can't be (readily) turned into a module, it would seem reasonable to have it built into GENERIC. Whilst we're discussing ATAPICAM, even after I make /dev/cd0[ac] mode 666, I can't write to it as a non-root user. Does anyone know the rationale for this and which particular EPERM is the culprit? I've had a quick look at the source but can't see nothing leapt out. >[ Peripheral note: DVDs are OK for backup, that is, but I much prefer tapes >for durability and long term storage. Quantum sDLT 220 drives rock. ] I can buy a DVD writer for about USD100. An SDLT drive is about two orders of magnitude more expensive. Likewise, the media is around two orders of magnitude more expensive. In $/GB, DLT is only 2-3 times as expensive but the capital cost is somewhat of a killer. -- Peter Jeremy
