Yes; when I update, my changes from the process in src/UPDATING generally augment what's there (e.g., to clear /usr/include & /usr/share/man before the make installworld). And the NIC that's in use (at home -- and most other places) on the laptop is iwn(4), so yes, there is a firmware blob: 4 1 0xc138a000 54e38 iwn5000fw.ko (Well, that particular line is from kldstat when it's running stable/9; I just checked the head slice, and the blob had been rebuilt (based on mtime), and has contents different from the contents in stable/9: g1-227(9.1-P)[3] md5 /{,S4/}boot/kernel/iwn5000fw.ko MD5 (/boot/kernel/iwn5000fw.ko) =3D 8f98e8f28c70fe801c73aec4f717973f MD5 (/S4/boot/kernel/iwn5000fw.ko) =3D a0150e03bfd307595ab37b0924252844 g1-227(9.1-P)[4] ls -lT !$ ls -lT /{,S4/}boot/kernel/iwn5000fw.ko -r-xr-xr-x 1 root wheel 345868 Oct 7 07:48:46 2012 /S4/boot/kernel/iwn5= 000fw.ko -r-xr-xr-x 1 root wheel 344416 Oct 7 04:51:11 2012 /boot/kernel/iwn5000= fw.ko g1-227(9.1-P)[5]=20 FWIW.) As noted, the message does not appear to be associated with (other) unwanted behavior, so I wouldn't consider this of earth-shattering importance. It just seemed rather odd, and I got to wondering if the developer who committed the change had intended this result. And if said result was actually of use to anyone. :-} Peace, david --=20 David H.
