|
A Python-based utility for configuring hibernation on Linux systems using a swap file.
|
|
This tool automates resume configuration for GRUB and initramfs and optionally creates a swap file of configurable size.
|
|
|
|
Designed for Arch-based systems (Arch Linux, Manjaro) and intended for automation and reproducible system setup.

## 🧪 Examples
|
|
|
|
Create a 40GB swapfile and configure hibernation interactively:
|
|
|
|
```bash
|
|
sudo setup-hibernate --create-swapfile --swap-size 40
|
|
```
|
|
|
|
Preview what would happen without actually doing anything:
|
|
|
|
```bash
|
|
sudo setup-hibernate --create-swapfile --swap-size 40 --preview
|
|
```
|
|
|
|
Non-interactive, suitable for automation:
|
|
|
|
```bash
|
|
sudo setup-hibernate --create-swapfile --swap-size 40 --non-interactive
|
|
```
