Yes. But:

You don't need this if you use
\ShellEscape{rm -f picts ; ln -s $HOME/test/picts picts}
in the first command.
This will remove an existing link before attempting to create a new
one, thus avoiding the creation of the link in the target dir (in some
ln implementations, there is the -n option which could also be used,
but this is not globally available and also implementation-specific).
I am surprised that this can happen, as we remove the link anyway after
compilation, but anyways ...

I think the wiki is a good place for this. I have added some
documentation:
