[instack-undercloud] puppet-stack-config.pp $pkg_upgrade_cmd default will always fail

[John Trowbridge]

Our default for $pkg_upgrade_cmd will cause a failure for any non-RedHat osfamily. While it is pretty likely that we have other places in TripleO that break for non-rpm distros, I think it is still worth fixing this up.

Further details from Alex Shultz in https://review.openstack.org/#/c/391473/2/elements/puppet-stack-config/puppet-stack-config.pp :

"""
  case $::osfamily {
    'RedHat': {
      $pkg_upgrade_cmd = 'yum -y update'
    }
    default: {
      warning('Please specify a package upgrade command for distribution.')
"""

This should either be a fail or we need to specify $pkg_upgrade_cmd = 'true' or something because the exec below will just error if $pkg_upgrade_cmd is undef.

[root@host ~]# cat t.pp
exec { 'test':
  command => $undef_variable,
  path => '/usr/bin',
  timeout => 0
}
[root@host ~]# puppet apply t.pp

I like the idea of setting $pkg_upgrade_cmd = 'true' combined with making the warning a bit more clear on how someone would add update support for their distro.

I tried adding low-hanging-fruit tag... but launchpad is not cooperating.

hmm... apparently needed a comment on the bug first?

    Fix package update cases

    This change addresses two issues with the existing
    puppet-stack-config. The first being if run on a non-RedHat osfamily,
    the existing code will fail with a non-helpful message. The second issue
    being that if update_packages is disabled, the resource dependency will
    fail because Exec['package-upgrade] is not defined.
