Hey Martin,

I don't see what your issue is, nothing has changed and this isn't
linked at all to snapd but rather a traditional linux feature.

What commands are you running?
$ ln -s /snap/bin/gtk3-demo foo
$ ./foo
works here
$ ls -l foo
lrwxrwxrwx 1 didrocks didrocks 19 nov.  14 10:37 foo -> /snap/bin/gtk3-demo

As well.
Please provide debug output.

Cheers,
Didier
