Augeas: Skipping because no files were changed

[Chris Lee]

I am trying to add two new options to grub.conf using augeas.
The code is as follows:

    augeas { 'grub.conf/8250_LAR':
            tag => chris1,
            incl    => '/boot/grub/grub.conf',
            lens    => 'Grub.lns',
            changes => [
                'set /title[1]/kernel/8250.nr_uarts 8',
                'set /title[1]/kernel/8250_core.nr_uarts 8',
            ],
    }

However nothing is added to /etc/grub.conf at all, and the puppet run completes as follows with debug.

Debug: Augeas[grub.conf/8250_LAR](provider=augeas): Augeas version 1.0.0 is installed
Debug: Augeas[grub.conf/8250_LAR](provider=augeas): Will attempt to save and only run if files changed
Debug: Augeas[grub.conf/8250_LAR](provider=augeas): sending command 'set' with params ["/title[*]/kernel/8250.nr_uarts", "8"]
Debug: Augeas[grub.conf/8250_LAR](provider=augeas): sending command 'set' with params ["/title[*]/kernel/8250_core.nr_uarts", "8"]
Debug: Augeas[grub.conf/8250_LAR](provider=augeas): Skipping because no files were changed
Debug: Augeas[grub.conf/8250_LAR](provider=augeas): Closed the augeas connection

Manually, Augeas appears to work fine:

augtool> set /files/boot/grub/grub.conf/title[1]/kernel/8250_core.nr_uarts 8
augtool> save
Saved 1 file(s)

I'd appreciate any ideas?


Thanks
Chris

This needs:

context => '/files/etc/grub.conf',

Actually in this case it needs:

context => '/files/boot/grub/grub.conf',

or:

context => '/files/etc/grub.conf',
incl => '/etc/grub.conf',

Thanks Ian,

I had tried with and without the context, also tried with set and setm, tried to include the values first... but nothing worked.

I was about to go insane and through to remove the trailing slash in the changes...

    augeas { 'grub.conf/8250_LAR':
            incl => '/etc/grub.conf',

            lens    => 'Grub.lns',
            changes => [

                'set title[1]/kernel/8250.nr_uarts 4',
                'set title[1]/kernel/8250_core.nr_uarts 4',
            ],
    }

 and now it works, with and without the context.. but I'll put it back in anyway just in case.

Thanks!

Chris
