Extract OpenBSD System Configuration
The target for this solution is to be able to extract the difference from a freshly installed OpenBSD system and the current state of working OpenBSD based appliance or server. Using this configuration package it should be easy to replicate the setup a new machine (possibly on a new version of OpenBSD).
The solution should try to determine system configuration through the following means.
- Check installed packages with
pkg_info -m - Check updated or new configuration files in
/etc,/var/cron - Find system management utilities in
/root/binand/or/usr/local - Changes in file permissions
The system use a fresh OpenBSD install to check changes against very similar to the sysmerge(8) utility.
This may be used as complement with other installation instructions for a OpenBSD based appliance or server.
The may also be an option to apply the changes interactively on a new system.
- New files should be installed
- Updated files should be merged (while keeping original)
- Deleted files should be moved to a temporary location
To make changes as relevant as possible the install process might be done in a virtual machine in the following steps.
- Install packages in the VM get default configuration files
- Diff between VM and running system to identify changes
