fstab merge vs overwrite on defaults

[shaiguitar]

Due to

ephemeral_lvm/attributes/default.rb

Lines 29 to 32 in 333581c

	default['ephemeral_lvm']['mount_point_properties'] = {
	options: ["defaults", "noauto"],
	pass: 0
	}

the cookbook will just merge the chef attributes set and not overwrite them. For example, with:

    "ephemeral_lvm": {
      "mount_point": "/mnt/mongodb",
      "mount_point_properties": { "options": ["defaults", "noatime","auto"], "paas": 0 }
    }

The end result fstab will be:

/dev/mapper/vg--data-ephemeral0 /mnt/mongodb ext4 defaults,noauto,noatime,auto 0 0

instead of having just the auto (and not both merged on top of each other). Is this intended behavior and/or something to do to fix?

looking at this, it's definitely intentional: https://github.com/rightscale-cookbooks/ephemeral_lvm/blob/master/recipes/default.rb#L69
