# System-related configuration
|
|
|
|
This Ansible playbook can install and configure various system-related things for you.
|
|
All the sections below relate to the host OS instead of the managed containers.
|
|
|
|
### swap
|
|
|
|
To enable [swap](https://en.wikipedia.org/wiki/Memory_paging) management (also read more in the [Swap](https://wiki.archlinux.org/title/Swap) article in the [Arch Linux Wiki](https://wiki.archlinux.org/)), add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
|
|
|
|
```yaml
|
|
########################################################################
|
|
# #
|
|
# system #
|
|
# #
|
|
########################################################################
|
|
|
|
system_swap_enabled: true
|
|
|
|
########################################################################
|
|
# #
|
|
# /system #
|
|
# #
|
|
########################################################################
|
|
```
|
|
|
|
A swap file will be created in `/var/swap` (configured using the `system_swap_path` variable) and enabled in your `/etc/fstab` file.
|
|
|
|
By default, the swap file will have the following size:
|
|
|
|
- on systems with `<= 2GB` of RAM, swap file size = `total RAM * 2`
|
|
- on systems with `> 2GB` of RAM, swap file size = `1GB`
|
|
|
|
To avoid these calculations and set your own size explicitly, set the `system_swap_size` variable in megabytes, example (4gb):
|
|
|
|
```yaml
|
|
system_swap_size: 4096
|
|
```
