Subject: How can I make space-saving and reliable backup/clone of Teo En 
Ming Linux 2020.03 (FINAL)?

Good day from Singapore,

I have recently *successfully* created my own custom Linux distribution 
called Teo En Ming Linux 2020.03 (FINAL), which is based on
Linux From Scratch (LFS) 20200302-systemd development book and Linux 
Kernel 5.5.7, on 12 March 2020.

Please refer to my redundant blog posts for more information about Teo 
En Ming Linux 2020.03 (FINAL).

The question is, how can I make space-saving and reliable backup/clone 
of Teo En Ming Linux 2020.03 (FINAL)?

If you are able to assist with or solve my Live CD/DVD ISO issues, I 
will be very grateful indeed. Currently, my Live CD/DVD boots with a 
Kernel Panic.

[ 13.362601 ] ---[end Kernel panic - not syncing: Attempted to kill 
init! exit code=0x00000200 ]---

Please advise.

Thank you very much.
