Manage alternatives symlinks.
Using puppet resource to inspect alternatives
root@master:~# puppet resource alternatives
alternatives { 'aptitude':
path => '/usr/bin/aptitude-curses',
}
alternatives { 'awk':
path => '/usr/bin/mawk',
}
alternatives { 'builtins.7.gz':
path => '/usr/share/man/man7/bash-builtins.7.gz',
}
alternatives { 'c++':
path => '/usr/bin/g++',
}
alternatives { 'c89':
path => '/usr/bin/c89-gcc',
}
alternatives { 'c99':
path => '/usr/bin/c99-gcc',
}
alternatives { 'cc':
path => '/usr/bin/gcc',
}
Using puppet resource to update an alternative
root@master:~# puppet resource alternatives editor
alternatives { 'editor':
path => '/bin/nano',
}
root@master:~# puppet resource alternatives editor path=/usr/bin/vim.tiny
notice: /Alternatives[editor]/path: path changed '/bin/nano' to '/usr/bin/vim.tiny'
alternatives { 'editor':
path => '/usr/bin/vim.tiny',
}
Using the alternatives resource in a manifest:
class ruby_193 {
package { 'ruby1.9.3':
ensure => present,
}
# Will also update gem, irb, rdoc, rake, etc.
alternatives { 'ruby':
path => '/usr/bin/ruby1.9.3',
require => Package['ruby1.9.3'],
}
}
include ruby_193Creating a new alternative entry:
alternative_entry { '/usr/bin/gcc-4.4':
ensure => present,
altlink => '/usr/bin/gcc',
altname => 'gcc',
priority => 10,
require => Package['gcc-4.4-multilib'],
}On RedHat, configuring an alternative using a family instead of a full path:
alternatives { 'java':
path => 'java-1.8.0-openjdk.x86_64',
require => Package['java-1.8.0-openjdk'],
}This module should work on any Debian and RHEL based distribution.
