Subject: [PATCH v2 4/8] tests/docker: preserve original name when copying libs
Date: Fri, 22 Jan 2021 18:18:50 +0000
Message-ID: <20210122181854.23105-5-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210122181854.23105-1-alex.bennee@linaro.org>

While it is important we chase down the symlinks to copy the correct
data we can confuse the kernel by renaming the interpreter to what is
in the binary. Extend _copy_with_mkdir to preserve the original name
of the file when asked.

Fixes: 5e33f7fead ("tests/docker: better handle symlinked libs")
