 ## How to specify multiple lines entries
 
 This is actually a yaml question, not a vault one but since I ask myself this frequently in this context here is how to put a multiple lines entry like a private key in vault (for a simple value, just don't use a `|`):

 Note that installing a fact does not make it exist before the next inventory run on the host. This can be problematic especially if you rely on facts caching to speed up ansible. Here
 is how to make ansible reload facts using the setup tasks (If you paid attention you already saw me use it above).

 Here is a working example of the pavucontrol app, a volume mixer I use :
-{{< highlight conf >}}
+```cfg
 exec --no-startup-id i3 --get-socketpath > /tmp/i3wm-socket-path
 for_window [instance="^pavucontrol"] floating enable
 bindsym Mod4+shift+p exec /home/julien/bin/i3dropdown -W 90 -H 50 pavucontrol pavucontrol-qt
-{{< /highlight >}}
+```
 
 To work properly, i3dropdown needs to have the path to the i3 socket. Because the command to get the socketpath from i3 is a little slow, it is best to cache it somewhere. By default
 i3dropdown recognises `/tmp/i3wm-socket-path`. Then each window managed by i3dropdown needs to be floating. The last line bind a key to invoke or mask the app.

 Can you see what happened for the last test? The break statement in a location stops all evaluation, and do not reevaluate the resulting path in any location. Nginx therefore tries to serve a file from the root directory specified for the server. That is the reason we do not get either `root` or `configs` as outputs.

 ## Introduction
 
 Now that I am mostly running OpenBSD servers I just use genkernel to build my custom configuration on each node with :
-{{< highlight sh >}}
+```sh
 eselect kernel list
 eselect kernel set 1
 genkernel all  --kernel-config=/proc/config.gz --menuconfig
 nvim --diff /proc/config.gz /usr/src/linux/.config
-{{< / highlight >}}
+```
 
 Bellow you will find how I did things previously when centralising the build of all kernels on a collab-jde machine, and distributing them all afterwards. Local nodes would only rebuild local modules and get on with their lives.

 ## Introduction
 
 Here is my go to set of commands when I upgrade a gentoo box :
-{{< highlight sh >}}
+```sh
 emerge-webrsync
 eselect news read
-{{< /highlight >}}
+```
 
 The news have to be reviewed carefully and if I cannot act on it immediately I copy paste the relevant bits to my todolist.
 
 ## The upgrade process
 
 I run the upgrade process in steps, the first one asking you to validate the upgrade path. You will also be prompted to validate before cleaning :
-{{< highlight sh >}}
+```sh
 emerge -qAavutDN world --verbose-conflicts --keep-going --with-bdeps=y && emerge --depclean -a && revdep-rebuild -i -- -q --keep-going; eclean --deep distfiles && eclean --deep packages && date
-{{< /highlight >}}
+```
 
 After all this completes it is time to evaluate configuration changes :
-{{< highlight sh >}}
+```sh
 etc-update
-{{< /highlight >}}
+```
 
 If a new kernel has been emerged, have a look at [the specific process for that]({{< ref "kernel_upgrades" >}}).
