+Package management is made with simplaret app, whose behaviour is detailed in its own document.
+The following sections will only show how simplepkg can be used to manage jails and template
+and create packages.
-Configuration
--------------
+Creating templates
+------------------
+
+Initially, simplepkg was built to help slackware install automation. To do that, it uses installation
+templates -- lists of installed packages, post-installation scripts and config files -- allowing the
+creation of installation profiles that can be used for system replication in other partition or even
+custom chroot building.
+
+Template creation is done with "templatepkg" script. To create a template called "my-slackware" containig
+the installed package list of your slackware installation, just type
+
+ templatepkg -c my-slackware
+
+The -c (or --create) flag tells templatepkg to create the /etc/simplepkg/templates/my-slackware folder
+with the following components:
-As an example, we'll create a jail based on the packages installed in your slackware
-system. Edit the config file /etc/simplepkg/simplepkg.conf:
-
- # /etc/simplepkg/simplepkg.conf
- JAIL_ROOT="/vservers" # where jails are placed
- SIMPLARET="simplaret" # package grabber program (can be swaret if you have it installed)
- SIMPLARET_CLEAN="1" # clean package cache before installation
- SIMPLARET_DELETE_DOWN="1" # clean package cache after the installation
- SIMPLARET_UPDATE="0" # issue an simplaret --update before install the jail
- SIMPLARET_PURGE_WEEKS="N" # delete packages older than N weeks from the cache
- PATCHES_DIR="/storage/package/patches" # where patches are placed
- DEFAULT_ARCH="i386"
- DEFAULT=VERSION="10.2"
- STORAGE="/storage/packages" # where simplepkg store packages
- PASSIVE_FTP="1"
-
-You should also put in /etc/simplepkg/repos.conf all package repositories you use, like this:
-
- ROOT-i386="http://slack.sarava.org/packages/slackware"
- REPOS-i386="slack-sarava%http://slack.sarava.org/packages/slackware/slackware-10.2/"
- ROOT-x86_64-10.2="http://darkstar.ist.utl.pt/pub/slamd64/"
- REPOS-x86_64-10.2="slamd-sarava%http://slack.sarava.org/packages/slamd64/slamd64-10.2/"
-
-Instead of simplaret you can use swaret to fetch packages and them your swaret.conf must
-be configured to use the same place as STORAGE to the package cache. In this case you cant
-keep installations and jails with multiple arquitetures and for that reason the use of
-simplaret is recommended.
+ - /etc/simplepkg/templates/my-slackware/my-slackware.d: template config files
+ - /etc/simplepkg/templates/my-slackware/my-slackware.s: post-installation scripts
+ - /etc/simplepkg/templates/my-slackware/my-slackware.perms: metadata for config files
+ - /etc/simplepkg/templates/my-slackware/my-slackware.template: installaed package list
+
+This four components are enough to store all slackware installation characteristics: the package list
+controls with applications are installed, the config file folder can contain all desired configurations
+for any installed application and the post-installation scripts take care of all procedures that should
+be executed exactly after the system installation. The my-slackware.perms file contains metadata for the
+saved config files, i.e, permission and ownership.
+
+If you want to build a template from a installation placed in another folder or partition thats not your
+current root dir, just type something like
+
+ templatepkg -c my-slackware /mnt/slackware
+
+where /mnt/slackware is the place where this alternative system is installed. After created, the template
+will contain just the installed package list or that folder. As the folder /var/log/packages of your
+installation doesn't keep information about the package installation order, its recommended that you
+manually edit the template's package list. To do that, just type
+
+ templatepkg -e my-slackware
+
+To add configuration files inside the template, type something like
+
+ templatepkg -a my-slackware /etc/hosts
+
+This should add /etc/hosts file to "my-slackware" template. Beyond just automatically copy the file
+when you install a new system using this template, simplepkg can also take care of every change that
+/etc/hosts can suffer on your system, such as file content or permission and ownership change. If you're
+also storing your templates in a subversion repository, you'll be able to track all changes it ever had.
+
+WARNING: avoid the storage in a template of config files that contains important security information
+such as passwords or secret keys. The prefered place to put such stuff is a secured backup.
Creating jails and replicating installations
--------------------------------------------
- templatepkg my-slackare
- mkjail jail my-slackware
+As long as your template was created and populated with the package list, configuration files and
+post-installation scripts (what will be treated in another section), your can replicate your slackware
+installation as simpler than typing the following command:
-The previous commands creates a template called my-slackware from based on your installed
-softwares listed in /var/log/packages and then creates a completely new slackware
-tree with all those packages in the folder /vservers/jail (depending on the value of JAIL_ROOT from
-your simplepkg.conf).
+ mkjail jail my-slackware
-If you want that some config files get copied or some scripts executed after install this jail,
-place in the folder /etc/simplepkg/my-slackware.d all your config files (preserving the file
-system hierarchy, i.e, /etc/simplepkg/my-slackware/etc/apache/httpd.conf) and the scripts at
-/etc/simplepkg/my-slackware.s/. The template vserver, which comes in the simplepkg package, has
-an example script to use with mkjail.
+This creates a fresh slackware tree at /vservers/jail with all packages listed in the template "my-slackware"
+and all saved config files. The package installation is made by simplaret app, that should be properly configured.
+The standard simplaret configuration should work for most situations.
-You can specify an alternative destination for your jail with a command like
+If you want to install your jail in a place other than /vservers (this standard location can be changed through
+simpleokg config file), say /mnt/hda2, just use something like that:
ROOT=/mnt mkjail hda2 my-slackware
-This does exactly what you think: installs slackware in /mnt/hda2 with exactly the same packages
+The above command does exactly what you think: installs slackware in /mnt/hda2 with exactly the same packages
you have on your system, replacing the need of the slackware installer!
-In case no template specified, mkjail uses the one called /etc/simplepkg/default.template.
+In case no template specified, mkjail uses the one stored /etc/simplepkg/default, if exists. Simplepkg already
+came if some pre-built templates at /etc/simplepkg/defaults/templates.
-If you keep your jails in JAIL_ROOT with the same name as the template you used to create it, its
-possible to use the command jail-update to copy all modifications made in the files which their
-counterparts are placed at /etc/simplepkg/jail-name.d. Then you can copy all configuration files
-you edited to the template folder and leave a crontab entry to everyday seek for changes and update
-the template. When you issue the command
+Post-installation scripts
+-------------------------
- jail-update
+Optionally, its possible to keep post-installation scripts inside a template. Such scripts are executed by mkjail
+exactly after a jail is installed and the template config files copied. To create or edit a post-installation
+script, just type
-all jails listed in /etc/simplepkg/jaillist are updated. This command also updates the package list
-of the template.
+ templatepkg -b my-slackware script-name.sh
-To add or remove packages from a template, you can just edit by hand the template file or use the
-command templatepkg with the -a (append) flag, which adds just the new installed packages in the
-template file.
+This adds the script-name.sh at "my-slackware" template. Mkjail passes two command line arguments to a post-install
+script: the upward folder and the jail's name ("/mnt" and "hda2" from our previous example). Then, an example script
+is something like that:
-If you want to create a template from a jail, use
+ #!/bin/bash
+ chroot $1/$2/ sbin/ldconfig
- templatepkg jail /vservers/jail
+Listing template contents
+-------------------------
-Metapackages
-------------
+To list available templates or the template content, use commands such as
-Another use for the templates is the creation of metapackegs: new users have lots of difficulties
-to track dependencies when installing a software. Using a template containing the name of all
-packages needed by some program allow users to easily install it through the command
+ templatepkg -l
+ templatepkg -l my-slackware
- metapkg --install program-name
+Removing files from a template
+------------------------------
-This seems like swaret or slapt-get, with the only difference in the way metapkg deals with
-dependence resolution. Slapt-get support the slack-required file, wich comes or not with the
-package. Swaret has its own tool for dependence matching.
+As you did to add files, you can easily remove then from a template, using a comand such as
-Simplepkg doesn't wish to substitute those two dependence checking modes, but offer an alternate
-way to distribute packages where dependences are resolved without an specific tool or a change
-in the package itself.
+ templatepkg -d my-slackware /etc/hosts
-A metapackage, i.e, all installed packages from a template, can be removed with
+This removes the file /etc/hosts from "my-slackware" template.
- metapkg --remove program-name
+Removing a template
+-------------------
-Upgrading jails
----------------
+To remove a template, just type
+
+ templatepkg -r my-slackware
+
+Updating a template
+-------------------
+
+Now that we just talked about creating templates and jails, its time to cover another application, this time
+used to keep a template always updated. Jail-commit is a script that copies all config file changes (content,
+permissions and ownership) from a installation to a simplepkg template.
+
+For instance, if one wants to copy all changes from /mnt/hda2 jail into "my-slackware" template, he or she
+just needs to type the following command:
+
+ jail-commit /mnt/hda2 my-slackware
+
+Not just the package list from "my-slackware" template is updated according the installed packages from
+/mnt/hda2/var/log/packages: all config files from "my-slackware" template are compared it the ones from
+the jail and in case of any difference they're copied from the jail back to the template. Permissions
+and file ownership commit into the template works at the same way.
+
+Jail-commit allows that a template to being kept always updated and mirroring the actual configuration
+of an installed system. But if you want just to commit into the template just the installed package
+list, simply type
+
+ templatepkg -u my-template
-Both the main installation (your root system) and your jails are upgraded with the command
-jail-upgrade: just adjust simplepkg.conf's PATCHES_DIR to where you store slackware patches
-(that can be rsync'ed everyday) and do a
+To make life even easier, there's also a feature of keeping a list of all installed slackware system in
+the box in the file /etc/simplepkg/jailist. This file, despite its use by simplaret (what is described
+in its own text), allow jail-commit to run with no arguments.
- jail-upgrade
+Suppose you have three slackware installations: the root system and two more:
-This will upgrade your main system and all jails living in JAIL_ROOT. To specify another
-folder, use
+ - /mnt/slackware-1 using "slackware-1" template
+ - /mnt/slackware-2 using "slackware-2" template
- ROOT=/otherroot jail-upgrade
+If your /etc/simplepkg/jailist has the following lines:
-If you want to upgrade just one specific jail,
+ /mnt/slackware-1
+ /mnt/slackware-2
- jail-upgrade jail-name
+then the command
-To use a patches folder other than PATCHES_DIR, e.g when you have jails with different
-slackware versions, use
-
- PATCHES=/alternative/patches/folder jail-upgrade jail-name
+ jail-commit
+
+will update both "slackware-1" and "slackware-2" templates according, respectivelly, the contents of
+/mnt/slackware-1 and /mnt/slackware-2. If you also have a template called "main", then jail-commit
+will sync the contents of your root system with that template.
+
+You can even add the following line at root's crontab
+
+ 20 4 * * * jail-commit
+
+so all your templates get updated everyday. If your system is configured to send emails, then crontab's
+jail-commit output you give a summary of yesterday changes your system suffered, both config file changes
+and package additions and removals.
+
+Restoring changes in a jail
+---------------------------
+
+A operação contrária ao que o jail-commit faz também é possível: suponha que você mexeu na configuração do sistema
+mas se arrependeu das alterações e deseja voltar a configuração para o modo como ela se encontra no seu template,
+basta usar o comando
+
+ jail-update /mnt/hda2 my-slackware
