Configuration

The following explains how this package behaves during install, re-install, upgrade and removal. For a manual configuration based on the resulting configuration files check out the last topic "Manual configuration / import"

Installation

kesl.ini can be modified to set some basic stuff like using a proxy server or a specific admin user account on initial installation etc.

For the rest it is recommended to use configuration files instead as explained in the next topic.

Settings

kesl does not backup nor restore your configuration during an upgrade or re-install but this package does.

The real configuration of kesl is done either by using the CLI command kesl-control and one of the --setXXXX options - or importing a config file.

This package uses the config file approach to be able to save and restore: all config files in /ect/kesl/ are being read during install, re-install or upgrade.

Once you have walked through the configuration possibilites available you will find quickly that loosing these configs could hurt a lot. Especially when you fully uninstall this pkg and re-install it somewhen later.

spoiler: On uninstall all /etc/kesl/<setting>.conf files will be removed - but NOT /etc/kesl/<setting>.conf.persistent

So to keep all the work you did another option is available: the use of persistent files:

For every file /etc/kesl/<setting>.conf you can simply copy it to <setting>.conf.persistent and it will never get overwritten or deleted by the installer.

Note: You can NOT choose any name for these <setting>.conf or <setting>.conf.persistent files!
Only those available can be used.

Examples:

sudo cp /etc/kesl/app.conf /etc/kesl/app.conf.persistent
sudo cp /etc/kesl/Update.conf /etc/kesl/Update.conf.persistent

Then edit the persistent file to your needs and on next upgrade, install, re-install the persistent file will be read and used - even when there's a newer configuration file from a running config.

PKGBUILD: Install

1. restoring persistent configuration from all /ect/kesl/<setting>.conf.persistent files
2. the default configuration (including the one restored from persistent files) will be saved automatically to /ect/kesl/<setting>.conf - overwriting any existing

PKGBUILD: Upgrade / Re-install

1. before the upgrade/re-install starts the current running configuration will be saved automatically to /ect/kesl/<setting>.conf - overwriting any existing
2. after the upgrade finished all /ect/kesl/<setting>.conf will be restored
3. all /ect/kesl/<setting>.conf.persistent files will be restored (so any persistent config will have precedence)

PKGBUILD: Remove

1. all /ect/kesl/<setting>.conf files will be removed but /ect/kesl/<setting>.conf.persistent are kept

Manual configuration / import

Of course you can modify these /ect/kesl/<setting>.conf or better /ect/kesl/<setting>.conf.persistent files and then use them to configure kesl independent from the above described package process. For that you just need to pick the right kesl-control task and feed it with that configuration file of your choice.
