# Swap
|
|
|
|
Because a Linux system requires swap to function properly install `zram-init`. To keep it simple, it will utilise RAM to store compressed swap.
|
|
|
|
Install it with:
|
|
|
|
```
|
|
# apk add zram-init
|
|
# rc-update add zram-init default
|
|
```
|
|
|
|
`zram-init` can be configured in `/etc/conf.d/zram-init`. The amount of devices and the size of zram can be changed here, for example:
|
|
|
|
```
|
|
num_devices=<n>
|
|
|
|
# swap - 500M
|
|
|
|
#size0=512
|
|
size0=`LC_ALL=C free -m | awk '/^mem:/{print int($2/4)}'`
|
|
```
|
|
|
|
Now the size of the swap device will be one fourth of the ram size. Reboot the computer or restart the service to check if it works.

Also be sure to read the [ArchWiki](https://wiki.archlinux.org/title/Zram) for more information.
