*cough* ... look again.

/var/tmp/otherdir/symdir/../datadir' => '/var/tmp/otherdir/datadir'

I read it fine the first time. 

/var/tmp/otherdir/symdir/../datadir

[download]

is equivalent to 

/var/tmp/datadir

[download]

and not equivalent to 

/var/tmp/otherdir/datadir

[download]

In "/var/tmp/otherdir/symdir/../datadir", the ".." is that of "mydir" which is a hard link to "/var/tmp".

Do like I did and test before contradicting someone. 

$ cd /var/tmp
$ mkdir mydir
$ mkdir datadir
$ mkdir otherdir
$ touch mydir/in_mydir
$ touch datadir/in_datadir
$ touch otherdir/in_otherdir
$ cd otherdir
$ ln -s ../mydir symdir
$ ls /var/tmp/otherdir/symdir/../datadir
in_datadir
$ perl -le'opendir $dh, $ARGV[0] or die; print for grep /in/, readdir 
+$dh' /var/tmp/otherdir/symdir/../datadir
in_datadir
