Original GitHub issue: https://github.com/konstruktoid/hardening/issues/170

Originally assigned to: @konstruktoid on GitHub.

Describe the bug

/usr/sbin/logrotate /etc/logrotate.conf exists with the following error:

error: /etc/logrotate.conf:30 duplicate log entry for /var/log/wtmp
error: /etc/logrotate.conf:37 duplicate log entry for /var/log/btmp

Worth noting that original issue seems to be coming from logrotate package: https://bugs.launchpad.net/ubuntu/+source/logrotate/+bug/1915759
(TLDR: maintainers seem to come to conclusion to comment out /var/log/[bw]tmp { ... } blocks in /etc/logrotate.conf and rely on their equivalents in /etc/logrotate.d/[bw]tmp)

Although I'm not entirely sure if this constitutes for a bug, given that package-supplied logrotate.conf is being overwritten by the file from this repo, perhaps it's worth considering fixing it here now, while anticipating upcoming fix in logrotate package.

To Reproduce

Run /usr/sbin/logrotate /etc/logrotate.conf as called from systemd and cron.

Expected behavior

No errors and exit code 0.

System (lsb_release -a):

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04 LTS
Release:        22.04
Codename:       jammy

Additional context

Same problem reported in logrotate package issue tracker: https://bugs.launchpad.net/ubuntu/+source/logrotate/+bug/1915759

Updated the config file for logrotate @bob-rove to make it match upstream.

I believe https://bugs.launchpad.net/ubuntu/+source/logrotate/+bug/1915759 can be closed since an up-to-date Focal and Jammy don't include the duplicate code.
