... But I'm doing a diff -ur /4.4lite/v1/4.4BSD-Lite/usr/src /4.4lite/v2/4.4BSD-Lite2/usr/src where both of the trees are cds mounted from my Nakamichi NBR-7. This is running -stable of a few days ago. I recall that others were having problems with this drive, but I've lost their names. It seems stable enough for me, and I've had to install no special patches. This is with the usual 486DX2-66, UltraStor 34F, 32M of memory. Now, this operation isn't what I'd call "fast," "speedy," or "quick." In fact, I'd call it down right *SLOW*. However, it does seem to be working OK. I imagine for small subsets of the tree that catting the files first to /dev/null on each of the disks then running the diff would give me a big win :-). BTW, I estimate that make world (a 9-10hr operation on my machine) is about 10-100 times faster than this test. So far it has been going for 20 minutes, but I'm loath to let it run to completion. I don't want to wear out my drive mechanism. :-) Warner P.S. Whoever added noauto to fstab, et al, is a saint in my book.
