	At least since FreeBSD 3.x-RELEASE

>Description:

	This is supposed to be for "mv slink another_partition"

[125] solaris: cd /tmp;	ln -s x y
[126] solaris: ll
lrwxrwxrwx   1 jin             1 Apr  7 10:32 y -> x
[127] solaris: mv y ~
[128] solaris: ll ~/y
lrwxrwxrwx   1 jin             1 Apr  7 10:32 /home/users/jin/y -> x

	This is what happened on FreeBSD mv:

[111] FreeBSD: cd /tmp
[112] FreeBSD: mkdir test
[113] FreeBSD: ln -s x y
[114] FreeBSD: mv y test
[115] FreeBSD: ll test
total 2
drwxr-xr-x  2 jin   wheel  512 Apr  7 10:34 ./
drwxrwxrwt  4 root  wheel  512 Apr  7 10:34 ../
lrwxr-xr-x  1 jin   wheel    1 Apr  7 10:34 y@ -> x	# ok for local mv

[116] FreeBSD: cd test
[117] FreeBSD: mv y ~
mv: y: No such file or directory			# failed HERE
[118] FreeBSD: echo abc > x
[119] FreeBSD: ll
total 3
drwxr-xr-x  2 jin   wheel  512 Apr  7 10:48 ./
drwxrwxrwt  4 root  wheel  512 Apr  7 10:34 ../
-rw-r--r--  1 jin   wheel    4 Apr  7 10:48 x
lrwxr-xr-x  1 jin   wheel    1 Apr  7 10:34 y@ -> x
[120] FreeBSD: mv y ~			# incorrect for crossing partition
[121] FreeBSD: ll ~/y
-rw-r--r--  1 jin  wheel  4 Apr  7 10:48 /home/users/jin/y
[122] FreeBSD: cat ~/y
abc
[123] FreeBSD: ll
total 3
drwxr-xr-x  2 jin   wheel  512 Apr  7 10:49 ./
drwxrwxrwt  4 root  wheel  512 Apr  7 10:34 ../
-rw-r--r--  1 jin   wheel    4 Apr  7 10:48 x


>How-To-Repeat:

	Just repeat above operatoins within the same/different partitions.

>Fix:

	If every one agree this incorrect, I can trace down the code to
	find a patch.
