Description
This module extends puppet with support for the Sabayon Linux distribution.
It adds support for:
- The Entropy package manager
- Managing
Sabayon Community Repository (SCR)definitions usingenman - Enabling and disabling entropy repositories
- Entropy package masks and unmasks
- Splitdebug installs for packages
- Using systemd as the default service provider

Beginning with sabayon
The types and providers within this module can be used without any special
setup, as long as the required packages are already installed. To let this
module take care of installing the required packages, simply include the
sabayon class.
class { 'sabayon': }
Usage
Installing packages using entropy
This module sets the entropy provider to be the default for Sabayon,
so no special configuration is required.
The provider supports package names in both the fully-qualified format, e.g.
package { 'net-misc/openssh':
ensure => installed,
}
Or the more verbose format:
package { 'ssh-server':
ensure => installed,
category => 'net-misc',
name => 'openssh',
}
The category specification is optional as long as the package name is unique.
For example you could install pip as that's (currently) unique, but you could
not install 'mysql' since there's no way to disambiguate between
virtual/mysql and dev-db/mysql.
Managing enman repositories
Install an available SCR repository using enman. The title is taken to be the
repository name by default, and must be available via enman. Use an ensure
value of present to install the repo, and absent to remove it.
enman_repo { 'community':
ensure => present,
}
Enabling and disabling entropy repositories
Installed repositories (whether system or SCR repositories) can be enabled and
disabled using the entropy_repo type.
To enable a repository, use:
entropy_repo { 'sabayon-limbo':
enabled => 'true',
}
To disable a repository (only if present), use:
if 'sabayon-limbo' in $facts['entropy_repos'] {
entropy_repo { 'sabayon-limbo':
enabled => 'false',
}
}
This type cannot currently install or remove repositories, only control the enabled state of existing repositories. The repository being managed must already exist on the system.
Masking packages
Entropy is very flexible in how to specify which packages can be masked, and supports some or all of the following in the atom specification.
All of these parameters are optional, but at least one must be specified
package(either fully qualified or unqualified package name)operator(<,<=,=,>=,>. applied to version)versionslotusetagrepo
The entropy_mask type also takes the following optional parameters:
target(The path to the mask file, defaults to/etc/entropy/packages/package.mask)
Examples
To mask all packages within the community repository by default
and later unmask specific packages, you could use something like:
entropy_mask { 'mask-community-by-default':
repo => 'community',
}
Alternatively, you could mask newer versions of a package
entropy_mask { 'mask-postgresql-9.5+':
package => 'app-shells/bash',
operator => '>=',
version => '9.5',
}
Or mask a package with an undesirable set of use flags, e.g. to ensure any installed version of openssh supports ldap, mask all versions of openssh which don't include ldap support with:
entropy_mask { 'openssh-without-ldap-support':
package => 'net-misc/openssh',
use => '-ldap',
}
The entropy_mask type directly writes to the mask file, rather than using the
equo mask command line. This is so that entries can be removed again when
using ensure => absent, something which equo doesn't yet provide support
for. All entries managed by puppet include the # Puppet Name: namevar
trailing comment. Puppet will completely ignore the existence of other entries
in this file, which means you could manually manage other entries in the file
if you wished, although this is not recommended since puppet would not be able
to remove unmanaged entries if you later decide you want them to be managed.
Unmasking packages
Unmasking packages works identically to masking packages, except using the
entropy_unmask resource. All the same parameters are supported.
Unmasks take precedence over masks, so assuming
in the example above you have masked everything in the community repository
you could enable installing a particular package from that repository again
using:
entropy_unmask { 'sublime':
package => 'app-editors/sublime-text',
}
The same caveats about managing the unmask file apply as with entropy_mask
above.
Enabling splitdebug for packages
Entropy splits debug information for packages into separate objects which are
installed at the same time as the package only if splitdebug is enabled
globally, or for specific packages listed in the package.splitdebug file.
This type behaves similarly to masks/unmasks and manages entries in the
splitdebug file to define packages for which debug information should be
installed. All the same parameters are supported as with entropy_mask.
entropy_splitdebug { 'kernel':
package => 'sys-kernel/linux-sabayon',
}
The same caveats about managint the splitdebug file apply as with the
entropy_mask type above.
Enabling splitdebug masks for packages
This type inverts the entropy_splitdebug behaviour, and prevents splitdebug
from being installed for matching packages even when otherwise enabled by an
entropy_splitdebug entry. Masks take precedence, and anything matched by an
entropy_splitdebug_mask entry will never have debug information installed.
All the same parameters are supported as with entropy_mask.
entropy_splitdebug_mask { 'kernel-4.8':
package => 'sys-kernel/linux-sabayon',
slot => '4.8',
}
The same caveats about managint the splitdebug file apply as with the
entropy_mask type above.
Managing package keywords
The entropy_keywords type allows managing entries in the package.keywords
file, which can set missing keywords on packages. A typical example is when
installing a 9999 version package straight from source control which hasn't
been marked as supported on any platform.
Parameters:
keyword: The package keyword to apply. Defaults to the OS architecutre, e.g.amd64if not specified, but other typical values might be~amd64,-*or**.package: Name of the package, maybe qualified or unqualified.operator: (<,<=,=,>=,>, applied to version)version: Restrict the keyword to a specifc version or range of versionsrepo: Restrict the keyword to packages from a specific repo
At least one of package or repo must be specified.
entropy_keywords { 'sublime-live':
package => 'app-text/sublime-text',
version => '9999',
keyword => '**',
}

Facts
entropy_repos
Provides a structured fact identifying the entropy repos present on the system including their enabled/disabled state, and whether they are enman or entropy repositories.
Example (in yaml format for readability):
---
sabayonlinux.org:
repo_type: "entropy"
enabled: "true"
sabayon-limbo:
repo_type: "entropy"
enabled: "false"
community:
repo_type: "enman"
enabled: "true"
locale
Identifies the system-wide default locale, as set by eselect.
This is used internally by the entropy package provider to run equo commands
using the correct locale.
operatingsystem
Overrides the detection of the operating system on Sabayon systems to Sabayon.
Limitations
This module is actively used by the developer against current Sabayon versions. Due to the rolling release nature of Sabayon, the module is provided as-is and cannot be guaranteed to always be in a working state. Updates are provided on a best-efforts basis.
