Hello, when trying to use dump on a directory containing a relative symlink to another subdirectory of the source, dump follows the symlink instead of copying it. The script at the following url reproduces a simple environment in which snapcraft exhibits the described error: https://gist.github.com/r4co0n/5766f0452cd5cc94e3b2b19959d48892 The following is snapcraft's debug output, note the additional "Checking if ...", "Found link ..." and "Migrating file ..." lines I added via some print() statements to find out what is going on.
