Puppet users - Jun 2007 - ensuring apt-get update is run first

I''m trying to do bootstrapping of debian boxes using pxeboot, debian
preseeding files and then puppet.  Over time I''d like more and more to
be done in puppet :)

One issue I''m hitting is the repository configuration.   Depending on
the node configuration, I''m supplying various files (with repository
information or proxy settings).  I then have an update line.  However
this needs to happen before _any_ Packages are acted upon and I can''t
figure out how to do that.

  file {
      "/etc/apt/sources.list.d/debian.list":
      content => template("repository/debian.list"),
      notify => exec[apt-update],
      before => exec[apt-update],
  }

  exec { apt-update:
      cwd => "/",
      path => [ "/usr/bin", "/usr/sbin" ],
      command => "/usr/bin/aptitude update",
      refreshonly => true,
      logoutput => true,
      # really want something like this
      # before => Package[*],
  }

Ideally I suppose the update should be part of the Package type (this
is updating the list of available packages, not updating an individual
package).

Ideally I''d like apt-update to run if anything under /etc/apt is
altered at all - however I couldn''t see anything to say that you can
subscribe to a directory recursively.

Many thanks,

Adrian

This requires the ability to specify a relationship with a whole  
class of resources -- basically, saying that all packages depend on  
this resource.

You can fake it for now by adding the following to the top of your  
configuration:

Package { require => Exec[apt-update] } # or whatever the exec is called

This still leaves some room for problems, in that if you specify a  
require manually, then it will override the default require, but as  
long as you keep that in mind, it''s not the end of the world.

I''d like to find a way to specify this kind of class relationship,  
since it''s occurring often in the package world and sometimes other  
places, too, but I don''t have an idea for how to do it yet.  Ideas  
are appreciated.

Just subscribe to the top-level dir:

file { "/etc/apt": recurse => true, checksum => md5 }

exec { "apt-get update": subscribe => File["/etc/apt"],
refreshonly
=> true }
