That means /tmp/link-test exists already, otherwise lstat returns -1.
Here is what I see if the link already exists when I run my script:
access("/tmp/pear", F_OK) = 0
access("/tmp/link-test", F_OK) = 0
unlink("/tmp/link-test") = 0
lstat64("/tmp", {st_mode=S_IFDIR|S_ISVTX|0777, st_size=4096, ...}) = 0
lstat64("/tmp/link-test", 0xbff229ec) = -1 ENOENT (No such file or
directory)
lstat64("/tmp", {st_mode=S_IFDIR|S_ISVTX|0777, st_size=4096, ...}) = 0
lstat64("/tmp/pear", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
symlink("/tmp/pear", "/tmp/link-test") = 0
lstat64("/tmp/link-test", {st_mode=S_IFLNK|0777, st_size=9, ...}) = 0
write(1, "link", 4link) = 4
write(1, "\n", 1
) = 1
write(1, "link", 4link) = 4
write(1, "\n", 1
) = 1
stat64("/tmp/pear", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
write(1, "differ", 6differ) = 6
So did you leave out those access() calls, and did they fail, or did the
unlink() fail perhaps?
