Description of problem:

Upon creating a custom drop-in file for PostgreSQL (postgresql-fs-mount-reqs.conf), I noticed that the installer intentionally removed this file during its execution.

Version-Release number of selected component (if applicable):
satellite-6.14

How reproducible:
When creating a custom configuration

Steps to Reproduce:

To reproduce the behavior where the custom configuration file for PostgreSQL is removed during the Satellite installation, you can follow these steps:

1. Navigate to the directory where PostgreSQL drop-in configurations are stored:

1. cd /etc/systemd/system/postgresql.service.d

2. Create a custom drop-in configuration file:

1. touch postgresql-fs-mount-reqs.conf

3. Verify the existence of the custom drop-in file:

1. ls -l
   The output should include `postgresql-fs-mount-reqs.conf`.
   rrr-. 1 root root 73 Dec 19 08:05 postgresql.conf
   rw-rr-. 1 root root 0 Jan 12 03:08 postgresql-fs-mount-reqs.conf

4. Run the Satellite installer:
satellite-installer -S satellite

5. Monitor the installer logs for any actions related to the custom drop-in file:

1. tail -f /var/log/foreman-installer/satellite.log

6. After the installation completes, check the contents of the directory:

1. ls -l
   rrr-. 1 root root 73 Dec 19 08:05 postgresql.conf
   The custom drop-in file may no longer be present.

Actual results:

After running the satellite-installer command for Satellite, I observed that the installer process removed the custom drop-in file, as evidenced by both the absence of the file and corresponding log entries indicating its removal.
the satellite installer appears to delete custom configurations during the installation process.

Expected results:

The expected result would be that the custom PostgreSQL drop-in configuration file (postgresql-fs-mount-reqs.conf) remains intact even after running the Satellite installer. The installer should not remove custom configurations that are essential for ensuring proper PostgreSQL startup dependencies, such as mount points.

Additional info:

Tested on satellite 6.13 and it does not remove it.
