mom, thats not all, if you wanna see diff, add this your nodeset file

```    default_apply_opts:
      show_diff:```


isn't the value then nil? I think it translates to {"default_apply_opts" =&gt; {"show_diff" =&gt; nil}}

but if you want better support for it: <https://github.com/voxpupuli/beaker-puppet/blob/166f2a829af05db5841b6258185f102882978682/lib/beaker-puppet/helpers/puppet_helpers.rb#L456> could be made aware of show_diff and an env var

no if the value ist nil it is treated as a optionless parameter. so it will result in only `--show_diff`. if you set anything it will be transformed into `--show_diff=anything`

```root@ubuntu2004:/etc/sysctl.d# rm 50-test.conf 
root@ubuntu2004:/etc/sysctl.d# cat test.aug 
set /files/etc/sysctl.d/50-test.conf/kernel.sysrq 438
set /files/etc/sysctl.d/50-test.conf/net.ipv4.conf.all.log_martians 1
save
root@ubuntu2004:/etc/sysctl.d# augtool -f test.aug 
Saved 1 file(s)
root@ubuntu2004:/etc/sysctl.d# ls -la 50-test.conf 
-rw-r--r-- 1 root root 54 Apr 14 11:56 50-test.conf```

so it works fine via the augtool :thinking_face:

try it. I tried it my way and it worked for me so i didn't test anything else

forgot to cat the file above:
```root@ubuntu2004:/etc/sysctl.d# cat 50-test.conf 
kernel.sysrq = 438
net.ipv4.conf.all.log_martians = 1```

yaml spec ist a bit fuzzy there no key and ~are resulting both in nil

yep, you’re right but I’m always confused with such “hanging” hash keys :slightly_smiling_face:

jea, you are right. its confusing to read

it looks like something is missing or next line is part of the hash

lib version was bumped in augeas v1.13.0 as I see..

theoretically it should be possible to use git bisect to find the breaking commit..

Just realised the problem is reproduced with Ubuntu 20.04's libaugeas.so.0.24.2

could be in the ruby-augeas bindings as well

actually I was wrong, puppet uses another library path.. will retry again

so it works with augeas 1.12.0 but doesn’t with 1.13.0

now it’s time to narrow it down even more :slightly_smiling_face:

anyone able to provide a review on <https://github.com/voxpupuli/puppet-dnsquery/pull/129> please :)
