GNU Linux Debian - very fast and easy semi-automatic online install Debian 11 (non-free)
many users have/had macbooks.
what was/still is great: OSX can be reinstalled over internet! (no more searching for licence keys or setup sticks/DVDs/CDs/)
given the fact – that once installed – GNU Linux Debian can boot (almost) anywhere, the fastest and easiest way to “install” it is to simply 1:1 copy it on whatever the user wants to boot from (harddisk or usb stick (some sticks can not be made bootable, try at least 3 different vendors)).
So… this install script 1:1 copy installs Debian 11 (non-free) on any laptop/desktop/server (depending on internet speed) very fast & easy.
The process can be automated (on similar hardware or on hardware where /dev/sda is always the device the user wants to 1:1 overwrite).
This script install process is almost like OSX 🙂 but “semi-automatic” to double ask, not to overwrite the wrong (USB attached?) disk.
- it comes with a full MATE Desktop and everything to get working (LibreOffice and Firefox and Thunderbird)
- it has the “cosmos” slideshow (love it!) background enabled per default
- the terminal comes with green on black for better readability
- it does not have a swap partition enabled, so the user can easily with gparted 1) extend the harddisk to it’s full capacity 2) create a swap partition
- English, Spanish, Chinese and German keyboard layout are active, should be possible to switch between them in the top right corner
todo: what is still missing
- what is still missing is:
- automatically calc (based on RAM size, would do as much swap as RAM) how much swap should be created
- extend the /root partition to full harddisk capacity minus the swap space
- create the swap partition and edit config files /etc/fstab and /etc/initramfs-tools/conf.d/resume for proper (as intended) functionality of the system
- apply this
- display a dancing penguin during first successfull boot and encourage user to do at least 5min of dancing to this funky music 🙂
WARNING!
- make sure to disconnect all devices (external harddisks, usb sticks, sdcards)
- less devices = less trouble and less accidentally overwriting a external harddisk or usb stick
- if the target device /dev/sdX contains important data, backup it up !first! (all data will be overwritten)
WHY NON FREE?
it’s based on the non-free version, because it is intended to allow new users that never tested GNU Linux Debian (with a MATE Desktop) a “it just works” turnkey experience.
Is the Free version better?
If the user has concerns about surveillance/spying and needs maximum privacy than it is probably better to start with the defautl GNU Linux Debian free version and usually all network-cards/NICs work out of the box (free drivers available 🙂 (but maybe not the wifi cards)
new users: workaround for this pitfall:

Problems might arise with the free version and wifi: (notebooks)
because then the user will probably have to install the appropriate closed source (#evil!) drivers from the the non-free repository with all the spying backdoors that a intel wifi driver might have (after all a network card, is like a small computer, inside a computer, ideal! but then if the BIOS is not LibreBooted… the Intel ME can not be disabled… (some OS allow to permanently disable Intel ME!!!).
… the fight for more privacy and security – seems never ending and goes on.

process complete? reboot & “it just works”?
congratz! do 1min of wiggle dance!

post processing:
want to use the complete harddisk not just the 100GBytes? two possibilities:
what the script will do:
- download a pre-installed Debian 11 image.gz and it’s sha512check-sum
- sha512 check the image (check the image is unaltered and intact)
- on the fly unpack and 1:1 write the image to /dev/sdX while showing a progress bar
