Jason - Thanks for responding. Also thanks for your help on freenode #freebsd (I'm on there as rcl sometimes)
I've run your script and this is what I get:
FreeBSD 9.0-CURRENT #0 r220986: Sun Apr 24 08:25:28 UTC 2011 [email protected]:/usr/obj/root/current/current/sys/GENERIC BEFORE /dev/null: empty File: "/dev/null" Size: 0 FileType: Character Device Mode: (0666/crw-rw-rw-) Uid: ( 0/ root) Gid: ( 0/ wheel) Device: 255,83886080 Inode: 23 Links: 1 Access: Tue Apr 26 20:00:07 2011 Modify: Tue Apr 26 20:00:01 2011 Change: Tue Apr 26 20:00:01 2011 crw-rw-rw- 1 root wheel - 0, 23 Apr 26 20:00 /dev/null AFTER /dev/null: empty File: "/dev/null" Size: 0 FileType: Character Device Mode: (0777/crwxrwxrwx) Uid: ( 0/ root) Gid: ( 0/ wheel) Device: 255,83886080 Inode: 23 Links: 1 Access: Tue Apr 26 20:00:08 2011 Modify: Tue Apr 26 20:00:08 2011 Change: Tue Apr 26 20:00:08 2011 crwxrwxrwx 1 root wheel - 0, 23 Apr 26 20:00 /dev/null
I see no real difference between our results except that my /dev/null starts as 666 and comes back as 777 and yours is always 777. Again, I'm not clear on the meaning of this PR - I will abandon and move on. It does seem that the PR should be either clarified or closed On Apr 26, 2011, at 3:55 AM, Jason J.
