+Repack live
+===========
+You might want to save the state of your live system to the usb stick. In order
+to do so, run the following commands:
+
+apt update
+apt-get install -y cpio pigz
+rm /etc/rc.local
+# remove '#' before allow-hotplug
+vi /etc/network/interfaces
+mount /dev/sda1 /mnt
+mv /mnt/initrd.gz /mnt/initrd.old
+cd /
+find . -xdev | cpio --quiet -H newc -o | pigz -9 > /mnt/initrd.gz
+umount /mnt
+
+iwd
+===
+With iwd you can force to use 5ghz. The following needs to be done to get iwd
+running.
+
+sudo apt-get update
+sudo apt-get install iwd
+
+cat <<EOF > /etc/iwd/main.conf
+[Rank]
+ BandModifier5Ghz=10
+EOF
+
+# Remove or comment out the following interfaces from /etc/network/interfaces
+# allow-hotplug wlp1s0f0
+# iface wlp1s0f0 inet dhcp
+# wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
+
+# Add the following interfaces to /etc/network/interfaces
+allow-hotplug wlan0
+iface wlan0 inet dhcp
+
+# Reboot
+reboot
+
+# Configure iwd:
+sudo iwctl
+device list
+station wlan0 scan
+station wlan0 get-networks
+station wlan0 connect SSID
+
+Deinstall Linux

+# Lets assume you have the following partioning
+
+(mini) [~] sudo parted /dev/nvme0n1 print
+Model: APPLE SSD AP0256Q (nvme)
+Disk /dev/nvme0n1: 251GB
+Sector size (logical/physical): 4096B/4096B
+Partition Table: gpt
+Disk Flags:
+
+Number Start End Size File system Name Flags
+ 1 24.6kB 524MB 524MB iBootSystemContainer
+ 2 524MB 101GB 100GB
+ 3 101GB 103GB 2500MB
+ 4 103GB 104GB 513MB fat32 boot, esp
+ 5 104GB 246GB 142GB ext4
+ 6 246GB 251GB 5369MB RecoveryOSContainer
+
+# Never delete the first, the second and the last partition because that either
+# renders your mac unbootable (first two) or unupgradable (last one). However
+# you can recover the system by using a second system if you screw up.
+
+# In the above example we need to delete the partition number 3 (stub partition
+# you can identify it by the size 2500 MB). The partition 4 (you can identtify
+# it by the fact that it is fat32 and the flags boot, esp). And the partition
+# number 5 (you can identify it by the fact that it is ext4).
+
+You delete the partitions by doing:
+
+# n is the partition number
+sudo parted /dev/nvme0n1 rm <n>
+
+# If you're asked if you want to proceed, say 'y'. If your asked if you want to
+# ignore, say, ignore.
