Replying to [comment:6 tornaria]:
> Thus, removing the use of `readlink -n` will break some common usage
while not fixing
The common usage I refer to is the following:
1. I install sage x.y in a directory {{{~/sage/sage-x.y}}}
2. I make a symlink {{{~/bin/sage -> ~/sage/sage-x.y/sage}}} so that the
sage command is available in my path [note the full path symlink].
This works fine right now, and would break if you remove "readlink -n".
----
NOTE: When "~/bin/sage" is a symlink with a relative path symlink, this
doesn't work, and "readlink -f" would work. However, this leads to other
breakup (this is the reason why #5852 was reverted and #6146 was not
developed further). If you want to fix this you should start with #5852
(comment 12).
