## Installation
If you don't have a GRUB theme installed, [check these out](https://www.gnome-look.org/browse?cat=109&ord=latest). I am currently using [this one](https://www.gnome-look.org/p/2227016).
If you don't have a GRUB theme installed, [check these out](https://www.gnome-look.org/browse?cat=109&ord=latest). I am currently using [this one](https://www.gnome-look.org/p/2227016). The installer expects `/boot/grub2/user.cfg` to contain a `set theme=/boot/grub2/themes/<theme>/<file>.txt` entry so it can locate the theme's `icons` folder.
### 1. Find the icons folder of your currently used GRUB theme
1) Run the installer from the repo root (it will sudo itself):
```bash
sudo awk -F= '/set theme=/ {f=$2; sub(/\/[^/]*$/, "", f); print f "/icons"}' /boot/grub2/user.cfg
./install.sh
```
should print something like `"/boot/grub2/themes/<theme>/icons`
What it does:
- Reads your active theme path from `/boot/grub2/user.cfg` and copies `bluefin.png` into its `icons/` directory.
- Installs `bls-add-bluefin.sh` to `/usr/local/sbin/` and the rpm-ostree drop-in to `/etc/systemd/system/ostree-finalize-staged.service.d/bluefin-icons.conf`.
- Reloads systemd and immediately applies `grub_class bluefin` to existing BLS entries so icons show up right away.
### 2. Copy bluefin icon to that folder
2) (Optional) Verify:
```bash
sudo cp bluefin.png /boot/grub2/themes/<theme>/icons/
```
### 3. Install helper script
```bash
sudo cp bls-add-bluefin.sh /usr/local/sbin/
sudo chmod 755 /usr/local/sbin/bls-add-bluefin.sh
```
### 4. Install rpm-ostree hook
```bash
sudo mkdir -p /etc/systemd/system/ostree-finalize-staged.service.d
sudo cp bluefin-icons.conf /etc/systemd/system/ostree-finalize-staged.service.d/
sudo systemctl daemon-reload
```
### 5. (Optional) Test helper script
```bash
sudo /usr/local/sbin/bls-add-bluefin.sh
grep -n '^grub_class' /boot/loader/entries/ostree*.conf
# Expected Result
/boot/loader/entries/ostree-1.conf
2: grub_class bluefin
/boot/loader/entries/ostree-2.conf
2: grub_class bluefin
```
