### Installation
Install aur package [zectl-pacman-hook](https://aur.archlinux.org/packages/zectl-pacman-hook/).
### Configuration
To keep more than 1 boot environment, use:
```
zectl set pacmanhook-prunecount=5
```
Be aware of your ``/boot`` size limitation.
To know ~ max prunecount you could set, try:
```bash
boot_size=$(du /boot | awk '{print $1}')
efi_size=$(df /efi --output=avail | sed '1d')
echo "$efi_size / $boot_size" | bc
```
We discuss about increasing max number of boot envs here:
https://github.com/johnramsden/zectl/issues/19
To disable the hook, use:
```
zectl set pacmanhook="no"
```
### Manual install
```
git clone https://github.com/eoli3n/zectl-pacman-hook
cd zectl-pacman-hook
makepkg -c
makepkg -si
```
