--- Comment #2 from Conrad Meyer <cem@freebsd.org> ---
Truss:
open(".",O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC,01) =3D 5 (0x5)
fstatfs(5,{ fstypename=3Dufs,mntonname=3D/,mntfromname=3D/dev/gpt/freebsd-r=
oot,fsid=3D
}) =3D 0 (0x0)
fstat(5,{ mode=3Ddrwxr-xr-x ,inode=3D42455429,size=3D512,blksize=3D32768 })=
 =3D 0 (0x0)
fchdir(0x5)                                      =3D 0 (0x0)
getdirentries(5,"\M^E\M-Q\M^G\^B\0\0\0\0\0\0\0\0"...,4096,{ 0x0 }) =3D 168 =
(0xa8)
fstatat(AT_FDCWD,"lINK-to-fILE",{ mode=3Dlrwxr-xr-x
,inode=3D42459218,size=3D4,blksize=3D32768 },AT_SYMLINK_NOFOLLOW) =3D 0 (0x=
0)
fstatat(AT_FDCWD,"fILE2",{ mode=3D-rw-r--r--
,inode=3D42459473,size=3D27,blksize=3D32768 },AT_SYMLINK_NOFOLLOW) =3D 0 (0=
x0)
fstatat(AT_FDCWD,"fILE",{ mode=3D-rw-r--r-- ,inode=3D42459474,size=3D19,blk=
size=3D32768
},AT_SYMLINK_NOFOLLOW) =3D 0 (0x0)
getdirentries(5,0x8006a8000,4096,{ 0x200 })      =3D 0 (0x0)
close(5)                                         =3D 0 (0x0)

So we see that find(1) is correctly using AT_SYMLINK_NOFOLLOW to obtain stat
information for the symlink, as well as the other files.  So either the ker=
nel
is broken, or the comparison is somehow broken.
