What were you trying to do that didn't work?

We always tell the customers to not use legacy directives anymore.
But it appears this is not always feasible because of bugs in the new directives.
See for example:

Works

$FileOwner syslog
$FileGroup adm
$FileCreateMode 0600

Doesn't work (files owned by root anyway)

module(load="builtin:omfile" Template="RSYSLOG_TraditionalFileFormat"
       fileCreateMode="0600" fileOwner="syslog" fileGroup="adm")

What is the impact of this issue to you?

Issue with what we tell the customers.

Please provide the package NVR for which the bug is seen:

rsyslog-8.2412.0-1.el9

How reproducible is this bug?:

Always

Steps to reproduce

1. Create "syslog:adm" user/group

   # useradd -N -M -r -g adm syslog

1. Configure rsyslog to create files as this user, in /etc/rsyslog.conf

   module(load="builtin:omfile" Template="RSYSLOG_TraditionalFileFormat"
          fileCreateMode="0600" fileOwner="syslog" fileGroup="adm")

1. Delete /var/log/messages and restart rsyslog

   # systemctl stop rsyslog
   # rm /var/log/messages
   # systemctl start rsyslog
   # ls -l /var/log/messages
   

Expected results

-rw-------. 1 syslog adm 816 Oct  6 15:02 /var/log/messages

Actual results

-rw-------. 1 root root 1178 Oct  6 15:01 /var/log/messages
