 Commit d6e4f58 - sim-sync: handle symbolic links more gracefully (1 year,
 6 months ago) <Roland Haas> introduced a bug that manifest in error
 messages of the form "mkdir: cannot create directory `/ET_Hack':
 Permission denied".

 Pull request is https://bitbucket.org/simfactory/simfactory2/pull-
 requests/21/simlib-correct-stripping-of-first-part/diff

 This should be backported to the release as it is very annoying to not
 even be able to use sim sync to transfer code.
