Comment 11 for bug 1895138

after the gather facts fix merged https://review.opendev.org/752681 I posted a partial revert https://review.opendev.org/#/c/753034/ (for the fix merged @ https://review.opendev.org/#/c/750443/ ) for verification.

in testing at https://77fcbb6bcb190ff77af8-4535b5f6c3d3d8c9a7fe219932ac3358.ssl.cf2.rackcdn.com/739457/29/check/tripleo-ci-centos-8-standalone-upgrade-ussuri/015cefa/job-output.txt

you can see the 'ensure DLRN dir is present' task is OK:
