Comment 6 for bug 1934190

It seems that the recent CIS benchmark implements the rule 4.2.3 correctly and this issue is not a CIS benchmark bug.

So the issue is somewhere between charms, CIS and the deb packages I think.

This is the example log of reproducing the issue with rabbitmq package inside a Bionic LXD container on my dev environment: https://pastebin.ubuntu.com/p/xRJbsGkGFZ/ . The workaround was to add 'rabbitmq' user to syslog group and after that re-installation succeeded and rabbitmq server started successfully from the post-install scripts.

Similar problems are observed during installation of percona-xtradb-cluster-server package: post-install script (the service is running under mysql/mysql user which doesn't have the access to /var/log anymore and post-install script keeps waiting for it to start):
