The installation phase fails due to the documentation.

I found the error:
lrwxrwxrwx /bin/sh -> dash
lrwxrwxrwx /bin/sh -> bash
indeed, split it into two lines would fix the issue
would you mind reporting this to upstream? it would be great if they can fix it in next release
Looks like it was merged upstream and is part of the 2.14.0 upstream release.
