[Puppet Users] escaping the "@" symbol

[bruce bushby]

Hi

I've been writing a little module to handle some grub settings on RHEL
6 and appear the have run into a silly little problem that I just
can't fix.

I've trying to append the string "crashkernel=128M@16M" to the kernel
line in my grub.conf. The following module works 100% if I leave out
the "@" symbol. Any ideas how I can escape the "@" ??

I know I can use "crashkernel=auto" .... but I would like to know how
to insert any string I choose....even an "@".

Thanks





init.pp:

class grub {
        include grub::grub

        grub::set {
                "timeout": value =>  10;
        }
        grub::insert {
                "/files/boot/grub/grub.conf/title/kernel/ro": value =>
 'crashkerne128M@16M';
        }
}




grub.pp:

class grub::grub {

        define set ( $value ) {
                $key = $name
                $context = "/files/boot/grub/grub.conf"
                augeas { "grub_conf/$key":
                        context => "$context",
                        onlyif  => "get $key != '$value'",
                        changes => "set $key '$value'",
                        incl    => '/boot/grub/grub.conf',
                        lens    => 'grub.lns',
                }
        }

        define insert ( $value ) {
                $key = $name
                $context = "/files/boot/grub/grub.conf"
                augeas { "grub_conf/$key":
                        context => "$context",
                        changes => "insert '$value' after \'$key'",
                        incl    => '/boot/grub/grub.conf',
                        lens    => 'grub.lns',
                }
        }

        file { "grub_conf":
                name => $operatingsystem ? {
                        default => "/boot/grub/grub.conf",
                },
        }

}
