I looked at this a little more. It seems that the object on the other
side of /dev/fd/X isn't always one that you have permissions on _after_
it's been opened.
> ls -l /dev/fd/2
lrwx------ 1 bruce bruce 64 Aug 30 16:16 /dev/fd/2 -> [0301]:7060
This means "device 3, 1, inode 7060".
> ls -li `tty`
7060 crw-rw-rw- 1 root tty 4, 193 Aug 30 16:16 /dev/ttyp1
Note the "7060".
> ls -li /dev/hda1
6237 brw-rw---- 1 root disk 3, 1 Dec 31 1969 /dev/hda1
That's the root partition. Note the "3, 1"
It's the permissions of /dev/ttyp1 that apply here, not those of /dev/fd/2 .
