Create a System Image:
- Download, and install Debian 10 using the Debian 10.4.0 XFCE AMD64 live media ("https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-10.4.0-amd64-xfce.iso").
- Login as administrator (the user account created during installation) on the Debian installation.
- Open the "Applications" menu (located top left), go to "System", and click "Xfce Terminal" (a terminal emulator).
- In terminal enter "sudo apt update".
- In terminal enter "sudo apt install xorriso live-boot live-build live-tools initramfs-tools squashfs-tools gdisk tar zip unzip".
- In terminal enter "sudo apt clean".
- Boot the Debian live media in try mode.
- Open the "Applications" menu (located top left), go to "System", and click "Xfce Terminal" (a terminal emulator).
- In terminal enter "sudo apt update".
- In terminal enter "sudo apt install xorriso squashfs-tools tar zip unzip gdisk".
- In terminal enter "sudo apt clean".
- In terminal enter "sudo mkdir '/media/debian-installation'.
- In terminal enter "sudo blkid', and note the device path of the Debian installation root partition (eg: '/dev/sda2').
- In terminal enter "sudo mount '/dev/sda2' '/media/debian-installation'
- In terminal enter "sudo mv '/media/debian-installation/etc/fstab' '/media/debian-installation/etc/fstab.original'".

- In Nano press "control" + "X" to exit. When prompted to save enter "y".
- In terminal enter "sudo tar -cpf '/media/system-image/OSP.tar' -C '/media/system-image/OSP' 'boot' 'rootfs.iso'".
- In terminal enter "sudo rm -r '/media/system-image/OSP'".
- In terminal enter "cd '/media/system-image' && sudo zip -r 'system-image.zip' 'OSP.tar' && cd -".
- In terminal enter "sudo rm '/media/system-image/OSP.tar'".
- Logoff the Debian live media. The system image is finished being created. You can move it where ever you want.
Install a System Image (UEFI):
- Login as Administrator on the Debian installation.
- If it isn't already connected, connect the device which the Debian system image will be installed on. All existing content on this device is going to be erased during the installation.
- In terminal enter "lsblk -a -p", find the device which the Debian system image will be installed on, and note the device path (eg: "/dev/sdc").
- In terminal enter "sudo sgdisk --zap-all '/dev/sdc'".
- In terminal enter "sudo sgdisk -g '/dev/sdc'".
- In terminal enter "sudo sgdisk -n 1:0:+128M '/dev/sdc'". Replace "128" with the size in Mebibytes you want the ESP (EFI System Partition) to be. If you don't what size to use, keep it at the standard 128.
- In terminal enter "sudo mkfs -t vfat '/dev/sdc1'". Replace "/dev/sdc1" with the device partition created in the last step (eg: If the drive used was /dev/sdc, then the partition is /dev/sdc1).
- In terminal enter "sudo sgdisk -n 2:0:+20G '/dev/sdc'". Replace "20" with the size in Gibibytes you want the OSP (Operating System Partition) to be. How large you make it depends on the size of your system image, and how large the device being installed to is. Keep in mind you'll want minimum about twice the size of the system image, so you have room for it, and an older version of it.
- In terminal enter "sudo mkfs -t ext4 '/dev/sdc2'". Replace "/dev/sdc2" with the device partition created in the previous step (eg: If the drive used was /dev/sdc then the partition is /dev/sdc2).
- In terminal enter "sudo sgdisk -n 3:0:+20G '/dev/sdc'". Replace "20" with the size in Gigabytes you want for an empty partition. This partition will be used for housing a flat-install on a temporary basis for creating updated system images. The rest of the time it will be empty. How large you make it depends on the size of your extracted system image, and how large the device being installed to is.
- In terminal type "sudo mkfs -t ext4 '/dev/sdc3'". Replace "/dev/sdc3" with the previously created partition (eg: if the drive used was /dev/sdc then the partition is /dev/sdc3).
- In terminal enter "lsblk -a -p", find the OSP, and note the device path (eg: "/dev/sdc2").
- In terminal enter "sudo mkdir '/media/system-osp'".
- In terminal enter "sudo mount '/dev/sdc2' '/media/system-osp'".
- In terminal enter "lsblk -a -p", find the drive where you saved the system-image, and note the device path (eg: "/dev/sdb1").

Install a System Image (BIOS):
- Login as Administrator on the Debian installation.
- In terminal enter "sudo apt update".
- In terminal enter "sudo apt install parted".
- If it isn't already connected, connect the device which the Debian system image will be installed on. All existing content on this device is going to be erased during the installation.
- In terminal enter "lsblk -a -p", find the device which the Debian system image will be installed on, and note the device path (eg: "/dev/sdc").
- In terminal enter "sudo parted -s '/dev/sdc' mklabel msdos".
- In terminal enter "sudo parted -s -a optimal '/dev/sdc' mkpart primary ext4 0% 20GiB".
- In terminal enter "sudo mkfs -t ext4 '/dev/sdc1'". Replace "/dev/sdc1" with the device partition created in the previous step (eg: If the drive used was /dev/sdc then the partition is /dev/sdc1).
- In terminal enter "sudo parted -s '/dev/sdc' set 1 boot on".
- In terminal enter "sudo parted -s -a optimal '/dev/sdc' mkpart primary ext4 20GiB 40GiB".

Use an Installation:
- Upon booting from the drive, choose either "Debian (Frugal Rambooting)" to boot-to-ram, or "Debian (Frugal)" to boot from disk. If you have an old version present you can also use the "Debian (Frugal Rambooting) [OLD]", and "Debian (Frugal) [OLD]" entries to boot those. The "Debian (Flat)" entry will only work when there is a flat-install present (eg: when creating an updated system-image), it has been configured to point to the appropriate filesystem UUID, and the fstab is up to date.

Notes:
- Tested with Debian 10.4.0 XFCE AMD64.
- These steps were updated from an older tutorial.
- Do NOT blatently run commands. Some expect you to substitute values!
- On the Debian live media the administrative account is "user", and the password is "live".
- The steps do not setup the installation with a swap partition (or file), because on many modern systems it isn't needed, and causes unwanted writes. However, this means you won't be able to "suspend" or "hibernate" the system. You can add one by creating one (eg: If using /dev/sdc, "sudo sgdisk -n 4:0:+16G '/dev/sdc'", then "sudo mkswap '/dev/sdc4'"), and then adding an entry for it in fstab when updating the system-image. A swap partition should be atleast the same size as your RAM (so that it can store all the RAM data). If your system has a moderate amount of RAM you may want to use double that size for the SWAP partition. If your system very little RAM you may want to use quadruple the amount of SWAP.
- Live-boot does not work well when multiple squashfs files exist on a device. It has a habbit (depending on the name) of loading multiple squashfs files at once. As a work around, these steps pack the squashfs files into ISO's which allows specifying the exact file to load.
- Live-boot does not support live-media-path's with periods, or underscores when booting to ram. Instead it will boot.
- The temporary flat-install created during updating must have the fstab configured or the xserver will fail at login, and startx will not be able to start it.
- The frugal install will not have a background image displayed in Grub, because this can't be configured in grub.cfg.
- When using "grub-install" in these steps "--bootloader-id='Debian Compressed Frugal'" is specified. Normally this sets the folder name used on the ESP (eg: "/EFI/Debian Compressed Frugal"), and the entry name used in the UEFI (eg: "Debian Compressed Frugal"). In these steps "--removable" is also used, which overrules the ID specification, and makes grub install to /EFI/BOOT on the ESP. It will also use the name "BOOTX64.EFI" instead of "grubx64.efi". UEFIs typically know to check ESPs for /EFI/BOOT/BOOTX64.EFI, which is why you can boot that boot manager when specifying to boot from a device entry. UEFIs typically don't know to search other directories (eg: "/EFI/Debian Compressed Frugal"), which means you can only boot the boot-manager if you have an entry (which grub would create) in your UEFI pointing to that EFI file. Because these steps use "--removable" there will be no entry; you will need to boot from the device entry instead.
- These notes don't take into consideration BIOS system, except for the steps on installing the system-image on a BIOS machine. Those steps don't take into consideration BIOS systems using GPT (GUID Partition Table).
- In these steps a Grub boot folder is created on the OSP of the frugal install. Alternatively "--boot-directory=" could have been used to place the grub folder on the ESP, or a seperate boot partition. You can also create a grub folder containing a grub.cfg that just points to another grub.cfg on another partition.
- "live-config" isn't installed, because it isn't needed for this type of installation. It's used for creating frugal installations with modified configs like: creating a new user, changing the hostname, auto-logins.
- These steps create a compressed squashfs using mksquashfs's default settings. Performance systems with ample RAM, and diskspace may wish to disable compression.
