[elbe-devel] [PATCH v2 4/9] tests efilesystem: Add deeplinks test for copy_filelist

[Olivier Dion]

From: Torben Hohn <torben.hohn at linutronix.de>

/bin -> usr/bin is located at the root level. This works with the
current implementation in copy_filelist(). But when a link is relative
and deeper in the directory hierarchy, things break.

Add a test for this case.
