Review request for mesos, Gilbert Song, Jie Yu, and Vinod Kone.
Bugs: MESOS-6327
https://issues.apache.org/jira/browse/MESOS-6327
Repository: mesos
Description
-------
When a layer overwrites a symbolic link with a regular file, the link
must be removed first, otherwise 'cp' would follow the link and
overwrite the target instead of the link itself.
