Kali Linux - Creating your own distro

A colic of mine was trying to act cute and said he wanted his own custom version of kali linux.
As remaster-sys might not work, ( i think ), went on to figure if it's really possible.
As he sucks in googling, here are the steps for my own reference.

Install Kali to a VM.
apt update && apt install curl git live-build
git clone git://git.kali.org/live-build-config.git
cd live-build-config
Inside the kali-config folder, there are various "environments" available.
I choose the LIGHT version as though it's a variant of the XFCE env, it's really light.
With this in mind, lets add some "special" packages that my colic wants.
Edit the config in kali-config/variant-light/package-lists/kali.list.chroot
Add your packages etc.
As he wanted to add custom "code and scripts" as well, add them to kali-config/common/includes.chroot/ folder. EG: root/Desktop/aaa.txt will make the aaa.txt appear on the root desktop.
To enable SSH on startup, 
echo ‘update-rc.d -f ssh enable’ >> kali-config/common/hooks/01-start-ssh.chroot
chmod 755 kali-config/common/hooks/01-start-ssh.chroot
Once done, build the image.
./build.sh --variant light --verbose
Drink coffee and the build ISO will be at: images/xxx.iso

VM Fusion Persistant Disk

Add a new hard disk to your VM Fusion.
Open up the VMX File in your editor.
Search for your workdisk
scsi0:1.fileName = "YOUROWKDISK-000001.vmdk"

Add in the following lines
scsi0:1.mode = "independent-persistent"
snapshot.disabled = "TRUE"
snapshot.action = "keep"

To take snapshot. Shut down the VM. 
Then take the snapshot

Blank screen after some dist-upgrade

So my kali was doing some dist-upgrade.
Took wayyyyy too long and i just killed it.
However, next reboot, everything was black. =_+''

After booting, press Ctrl+Alt+F1~F12.
This should get you a terminal.
Login as root
dpkg --configure -a
WAIT PATIENTLY ( which i failed )
Once done, reboot, volia.

Auto Backup MYSQL DB table structure

Usually during coding, one would often forgot about the MySQL databases structure.
I would usually check in my code but not my DB design.

Below is a sh file that backup the MySQL table structure.
Not the best script. But it does the job.

#!/bin/bash

Host=localhost
BDir=/root/SQLStructureBackup/

Dump="/usr/bin/mysqldump -d -h $Host -u BACKUPUSER -pSOMEPASSWORDHERE "
MySQL=/usr/bin/mysql

Today=$(date +%Y-%b-%d)

# Get a list of all databases
Databases=$(echo "SHOW DATABASES" | $MySQL -u BACKUPUSER -pSOMEPASSWORDHERE)

for db in $Databases; do
        date=`date`
        file="$BDir/$Today-$db.sql.gz"
        echo "Backing up '$db' from '$Host' on '$date' to: "
        echo "   $file"
        $Dump $db | gzip > $file
done
