I'd like to look at the following issues:

1. I'd like to understand what exactly is failing when the fix is not applied.

2. The test case is failing with the fix applied.


Regarding (1), you responded:

Thanks for the explanation. The concept is already clear from your patch
description. Do you have an example of a failing ln command and which
filesystems the source and the destination are on, for the test case you added?

Because I interpret --exclude-path usr as "don't copy usr", but
meta-isar/scripts/lib/wic/canned-wks/sdimage-efi.wks contains only / and /boot.
If it complained about / and /boot, then I'd expect it to fail also without
--exclude-path usr.


With kind regards,
Baurzhan.
