Puppet does not recognize bind mounts

[Michael Watters]

I'm having an issue with puppet repeatedly attempting to mount resources which are configured as bind mounts on one of my nodes.  Here is a copy of the relevant lines from my manifest.

$koji_fedora_releases = ['28', '29', '30']

$koji_fedora_releases.each |$release| {

    ['released', 'testing'].each |$tag| {

        mount { "/pub/fedora/org/${tag}/${release}":

            ensure => mounted,

            device => "/storage/projects/koji/repos-dist/aos-${release}-${tag}/latest",

            fstype => 'none',

            options => 'rw,bind',

        }

    }
}

The agent is able to successfully apply these resources however it attempts to remount the directories every time that puppet runs.  For example, here is the output on the agent side.

Notice: /Stage[main]/Site::Fileserver01/Mount[/pub/fedora/site/candidates/30]/ensure: current_value unmounted, should be mounted (noop)

These lines are repeated for each bind mount resource.

How does puppet actually verify that a device is mounted?  The source directories *are* mounted and I'm able to access data in each directory without an issue.

Hello,

I'm unable to reproduce this behavior. To see about which mounts Puppet knows about, use 'puppet resource mount' or 'puppet resource mount
/pub/fedora/site/candidates/30'

# puppet resource mount /mnt/home
mount { '/mnt/home':
  ensure  => 'mounted',
  device  => '/home',
  dump    => '0',
  fstype  => 'none',
  options => 'rw,bind,seclabel,relatime,errors=remount-ro',
  pass    => '0',
  target  => '/etc/fstab',
}

Thanks.  I believe the issue may be that we are bind mounting paths that are bind mounts themselves.  I found another way to accomplish what I need using file_line resources so everything is mounted when the system boots.
