grub.lns unable to handle password entries in grub.conf for specific titles

[droyden]

Grub.lns is currently unable to handle a password entry within a specific title (encountered under RHEL6).

It returns this error:

Could not evaluate: Augeas didn't load /boot/grub/grub.conf with Grub.lns: Iterated lens matched less than it should (line:27, character:0)

When line 27 is:

password --md5 <encrypted password>

or

password --encrypted <encrypted password> 

Full grub.conf is:

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
password --encrypted <other encrypted password>

This can be demonstrated via the example puppet manifest:

    kernel_parameter { "clocksource":
            ensure => present,
            value  => "acpi_pm",
            target => "/tmp/grub_nopasswd.conf",
    }

Error: /Stage[main]/Main/Kernel_parameter[clocksource]: Could not evaluate: Augeas didn't load /tmp/grub_nopasswd.conf with Grub.lns: Iterated lens matched less than it should (line:27, character:0)
