### Create Encrypted Drive

```bash
# Create an encrypted drive
sudo cryptsetup luksFormat

# LUKS Disk Encryption can use up to 8 key slots to store passwords. We can use these keys to auto mount LUKS device.
# cryptsetup luksDump /dev/sda

# Create a lukskeys
mkdir -p /home/ducoterra/.lukskeys

# Generate key
dd if=/dev/random bs=32 count=1 of=/home/ducoterra/.lukskeys/btr_backup

# Change key mode
chmod 600 /home/ducoterra/.lukskeys

# Luks add a key
sudo cryptsetup luksAddKey /dev/sda /home/ducoterra/.lukskeys/btr_backup

# Get UUID of disk with
sudo blkid /dev/sda1

# Add key to crypttab
echo 'btr_backup UUID=1d7ce570-e695-47a0-9dda-5f14b5b20e21 /home/ducoterra/.lukskeys/btr_backup luks' >> /etc/crypttab

# Create read-only backup mount point
sudo btrfs sub create /mnt/btr_backup
sudo btrfs property set /mnt/btr_backup ro true

# Add to fstab
echo '/dev/mapper/btr_backup /mnt/btr_backup btrfs x-systemd.device-timeout=0,x-gvfs-show,x-gvfs-name=btr_backup,ssd,nofail,noatime,discard=async,compress=zstd 0 0' >> /etc/fstab

# close (or fix issues)
sudo cryptsetup luksClose backup0
```

### Create BTRBK Config

`sudo vim /etc/btrbk/btrbk.conf`

```conf
snapshot_create         ondemand
snapshot_preserve_min   2d
snapshot_preserve       14d
snapshot_dir snapshots

target_preserve_min     no
target_preserve         20d 10w *m

volume /mnt/btr_pool
	target       /mnt/btr_backup
	subvolume    root
	subvolume    home
```

### Create Systemd Timer

`sudo vim /etc/systemd/system/btrbk.service`

```conf
[Unit]
Description=Runs btrbk with config file at /etc/btrbk/btrbk.conf

[Service]
ExecStart=btrbk -c /etc/btrbk/btrbk.conf -v run
```

`sudo vim /etc/systemd/system/btrbk.timer`

```conf
[Unit]
Description=Run btrbk every hour

[Timer]
OnCalendar=hourly
AccuracySec=10min
Persistent=true
Unit=btrbk.service

[Install]
WantedBy=timers.target
```

### Test, Start and Enable service

Test your service:the available storage space on our NAS to the iSCSI target and the other half

```bash
sudo btrbk -c /etc/btrbk/btrbk.conf -v run
```

Enable your service:

```bash
sudo systemctl start btrbk.timer

sudo systemctl enable btrbk.timer
```

### Minecraft

1. You can find extra java versions at /etc/alternatives
2. You need to `dnf install xrandr` to launch any modpacks
3. You can create a desktop icon by putting this at ~/.local/share/applications/*.desktop:

```
[Desktop Entry]
Encoding=UTF-8
Name=Technic Launcher
Exec=/usr/bin/java -jar /home/ducoterra/Applications/TechnicLauncher.jar
Icon=/home/ducoterra/.icons/minecraft-launcher.png
Type=Application
Categories=Games;
```

### Firewall CMD

1. Enable firewall

```bash
systemctl start firewall-cmd
systemctl enable firewall-cmd
```

2. Set default behavior to drop everything

```bash
firewall-cmd --set-default-zone=drop
systemctl reload firewall-cmd
```

## Backups

### Full system backup

In the event you need to restore your system from a disaster do the following:

1. Reinstall fedora via a live image
2. After install, disk should be mounted at /mnt/sysimage
3. Copy the new fstab and crypttab to somewhere safe
4. rsync -av [etc, home, opt, root, usr, var]
5. `mount /dev/Y /mnt/sysimage/boot`
6. `mount /dev/Z /mnt/sysimage/boot/efi`
7. `mount --bind /dev /mnt/sysimage/dev`
8. `mount --bind /proc /mnt/sysimage/proc`
9. `mount --bind /sys /mnt/sysimage/sys`
10. `chroot /mnt/sysimage`
11. Edit fstab and crypttab so they match the new partitions
12. Update /etc/default/grub to match the new luks uuid
13. grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
14. reboot

## Libvirt

### Snapshots on secure-boot VMs

```bash
# list snapshots
qemu-img snapshot -l win10.qcow2

# create a snapshot
qemu-img snapshot -c 1-welcome win10.qcow2

# restore a snapshot
qemu-img snapshot -a 1-welcome win10.qcow2
```

### Connecting to Truenas via virt-manager

You should be able to use the following custom URL:

```text
qemu+ssh://root@driveripper.reeserelease.com/system?socket=/run/truenas_libvirt/libvirt-sock
```

This assumes the correct socket path from `/etc/libvirt/libvirtd.conf` and ability to log in as the root user via ssh.

## bluetooth

### Airpods

Edit: /etc/bluetooth/main.conf
Set ControllerMode = bredr

restart bluetooth service
connect airpods
comment line out
restart bluetooth service again

## ZRAM

Edit /etc/systemd/zram-generator.conf

```conf
[zram0]
zram-size = min(ram / 2, 16384)
compression-algorithm = lzo-rle
options =
writeback-device = /dev/zvol/tarta-zoot/swap-writeback
```

## Automatic Disk Decryption with TPM2

https://gist.github.com/jdoss/777e8b52c8d88eb87467935769c98a95

```bash
# Add decryption key to tpm. 
systemd-cryptenroll --tpm2-device=auto --tpm2-pcrs=0+2+4+7 /dev/nvme0n1p3

# Wipe old keys and enroll new key. You have to execute this command again after a kernel upgrade.
systemd-cryptenroll /dev/nvme0n1p3 --wipe-slot=tpm2 --tpm2-device=auto --tpm2-pcrs=0,2,4,7

# Add tpm2 configuration option to /etc/crypttab
luks-$UUID UUID=disk-$UUID none tpm2-device=auto,discard

# Add rd.luks.options=tpm2-device=auto to grub
grubby --args="rd.luks.options=tpm2-device=auto" --update-kernel=ALL

dracut -f
```

## Firefox GPU Rendering

https://community.frame.work/t/linux-battery-life-tuning/6665

```bash
dnf install intel-media-driver intel-gpu-tools
```

Type in about:config in the address bar and hit enter.

Set media.rdd-ffmpeg.enabled, media.ffmpeg.vaapi.enabled and media.navigator.mediadatadecoder_vpx_enabled to true.

Close and reopen your browser

Run the command sudo intel_gpu_top, play a 4k video and check whether the Video section is above 0.00%

## Gnome Software Updates (packagekitd and software)

To prevent Gnome Shell from starting Software open Settings->Search and disable Software from there.

Disable auto-updates

```bash
sudo systemctl disable packagekit
sudo systemctl stop packagekit

dconf write /org/gnome/software/allow-updates false
dconf write /org/gnome/software/download-updates false
```
