$ adt-run .// --setup-commands='apt-get update' --- lxc -es adt-utopic

runs fine but here I wanted to look at which files were created by adt-run.

This happens because you put your --output-dir *within* the tested tree. This generally easily leads to recursive effects, as that tests tree needs to be copied to testbeds while having active files in the output dir. It's better to use /tmp/results/ or anything not inside the tests tree.

I'll commit a patch which at least avoids that particular issue.

This bug was fixed in the package autopkgtest - 3.8.1

---------------
autopkgtest (3.8.1) unstable; urgency=medium

  * If the testbed does not have root privileges (e. g. missing sudo
    password), install click packages with pkcon and skip the AppArmor rule
    adjustment. This makes non-root click tests at least work for
    non-Autopilot cases. (LP: #1384417)
  * Make --shell-fail also apply to test dependency installation failure.
  * Run root tests through "su" as well (if possible), to ensure that these
    also get a proper PAM/logind session with all runners. (LP: #1393474)
  * Skip the test_tmp_install tests if apt-get download does not work. This
    might happen in some build environments which completely disable
    networking or don't have working apt-get download for some reason.
    (Closes: #769687)
  * Don't put the log FIFO into the output directory. This avoids keeping it
    in --output-dir, which fails if the output dir happens to be in the tested
    tree itself. (LP: #1393426)
  * adt-setup-vm: Don't purge man-db. It uninstalls way too much on images
    which aren't just minimal environments.
  * adt-setup-vm: Drop bogus "X-Start-Before" line in generated init.d script.
    (Closes: #770517)
  * Respect DEB_BUILD_OPTIONS=nocheck (side issue in #769687)
