Hi,

I've came across an oddity in devfs.  The size of a symlink is the length
of the "symbolic name", not the one of the target.

Consider:

$ ls -la /dev/ | grep ^l
lrwxr-xr-x   1 root  wheel    3 13 Feb 16:01 dvd@ -> acd0
lrwxr-xr-x   1 root  wheel    4 13 Feb 17:01 kbd0@ -> atkbd0
lrwxr-xr-x   1 root  wheel    3 13 Feb 16:01 log@ -> /var/run/log
lrwxr-xr-x   1 root  wheel    4 13 Feb 17:01 net1@ -> net/fxp0
lrwxr-xr-x   1 root  wheel    4 13 Feb 17:01 net2@ -> net/lo0
lrwxr-xr-x   1 root  wheel    4 13 Feb 16:02 net3@ -> net/ndis0
lrwxr-xr-x   1 root  wheel    6 13 Feb 17:01 stderr@ -> fd/2
lrwxr-xr-x   1 root  wheel    5 13 Feb 17:01 stdin@ -> fd/0
lrwxr-xr-x   1 root  wheel    6 13 Feb 17:01 stdout@ -> fd/1
lrwxr-xr-x   1 root  wheel    7 13 Feb 17:01 urandom@ -> random

against:

$ ls -l /sys
lrwxr-xr-x  1 root  wheel  11 13 Feb 12:12 /sys@ -> usr/src/sys

Is this considered a bug or a feature? :-)

regards,
le
