-===== Clone only a directory =====

-===== Reduce time that is used to raise network interfaces =====
-As root, create the "**networking.service.d**" directory if it does not already exist and create/modify "**reduce-timeout.conf**"
-  mkdir /etc/systemd/system/networking.service.d
-  vi reduce-timeout.conf
- Then add this to your "**reduce.timeout.conf**" file
-  [Service]
-  TimeoutStartSec=XX
- <note>**XX** is the time in seconds that you want the system to wait</note>
 ===== Disable swap =====

 After some time of lecture, I found out that there wasn't a config file with a lease-file option.
-===== Create a clean raspbian image =====
-    sudo dd if=/Users/<username>/Downloads/2019-04-08-raspbian-stretch-lite.img of=/dev/rdisk<sd card number> bs=4m
-<note important>Do the following 3 steps **BEFORE BOOTING** your raspberry pi</note>
-Before modifying **cmdline.txt** and **config.txt**, **BACKUP THEM**!
-    cp -p cmdline.txt cmdline.txt.original
-    cp -p config.txt config.txt.original
-Once you have finished, change the output console device and remove the script that autoexpands / partition size at first startup.
-    vi cmdline.txt
-    console=serial0,115200 console=tty1 -> console=ttyAMA0,115200
-    delete init=/usr/lib/raspi-config/init_resize.sh
-Don't forget to enable this option, otherwise you won't be able to communicate to your raspberry pi throught raspberry debug port (TTL-232R-RPi).
-    vi config.txt
-    add this : enable_uart=1
-    /dev/root       1.6G  978M  538M  65% /
-    devtmpfs        460M     0  460M   0% /dev
-    tmpfs           464M     0  464M   0% /dev/shm
-    tmpfs           464M   12M  452M   3% /run
-    tmpfs           5.0M  4.0K  5.0M   1% /run/lock
-    tmpfs           464M     0  464M   0% /sys/fs/cgroup
-    /dev/mmcblk0p1   43M   22M   21M  51% /boot
-    tmpfs            93M     0   93M   0% /run/user/1000
-Now, resize the / partition and create a new one. As root, type :
-    fdisk /dev/mmcblk0
-Your partition table should look like this :
-    Device         Boot Start     End Sectors  Size Id Type
-    /dev/mmcblk0p1       8192   96042   87851 42.9M  c W95 FAT32 (LBA)
-    /dev/mmcblk0p2      98304 3522559 3424256  1.6G 83 Linux
-Delete the / partition, and create a new one (primary) which starts at **THE SAME POSITION** as the one you have  just deleted, in my case 98304.\\
-In the **fstab**, replace **PARTUUID** by /dev/mmcblk0p<partition number>. Reboot your raspberry pi and then tell your system you have resized a partition by typing :
-    resize2fs /dev/mmcblk0p<partition number>
-After creating the partition that will be mounted at /media/data, **reboot** your raspberry pi. Then, turn it into an ext4 partition, and add it to **fstab**.
-    mkfs.ext4 /dev/mmcblk0p3
-Now, it's time to test what you have done.

-===== Rename username =====

-    sudo mount -o remount,rw /
-    sudo su passwd root
-And then enter the new password you want.
-    usermod -l acdsn pi
-    usermod -m -d /home/acdsn acdsn
-Set a password to the user
-    passwd acdsn
-===== Rename group =====
-    groupmod --new-name acdsn pi
-===== Rename hostname =====
-    vi /etc/hostname
-Replace the existing hostname by the new one.
-===== Generate ssh keys =====
-    ssh-keygen -t rsa -b 2048
