# Kaiten-yaki : Yet another full disk encryption for GRUB/Linux
|
|
Kaiten-yaki is a script set to help you to make a full disk encryption install to your desktop system.
|
|
|
|
Followings are the list of functionality.
|
|
- Support Ubuntu and Void Linux.
|
|
- Install from LiveCD/USB.
|
|
- Invoke GUI/TUI installer at the middle of script execution, for the ease of installation.
|
|
- Automatic detection of BIOS/EFI firmware and create MBR/GPT, respectively.
|
|
- Support to install multiple distributions in a LUKS partition.
|
|
- The "/boot" is located in the same logical volume with the "/".
|
|
- The swap logical volume is located inside encrypted volume.
|
|
- You need to type a passphrase only once in the boot sequence.
|
|
|
|
With the configuration parameters, you can customize each installation. For example, you can configure the system to have 2, 3 or 4,... distributions in a HDD/SSD, as you want.
|
|
|
|
Following is the HDD/SSD partitioning plan of these scripts ( In case of BIOS, the disk has MBR and doesn't have EFI partition, while it is depicted here).
|
|
|
|
|
|
|
|
The logical volume size of each Linux distribution (LVROOTSIZE) can be customized from a configuration parameter. Also, the swap volume size is customizable.
|
|
|
|
As depicted above, the LVM volume group has only one physical volume.
|
|
|
|
# Tested environment
|
|
These scripts are tested with following environment.
|
|
- VMWare Workstation 15.5.7 ( EFI/BIOS )
|
|
- Ubuntu 20.04.2 amd64 desktop
|
|
- Ubuntu Mate 20.04.2 amd64 desktop
|
|
- void-live-x86_64-20210218-mate.iso
|
|
- void-live-x86_64-musl-20210218-mate.iso
|
|
- void-live-x86_64-20210218.iso
|
|
|
|
# Installation
|
|
Start the PC with the LiveCD/LiveUSB of the distribution to install. Download this repository from github, and expand it.
|
|
|
|
Then, go to script directory and follow the procedure in the [INSTALL.md](INSTALL.md)
|
|
|
|
# Known issues
|
|
If you install two or more Void Linux in to the EFI system, only the last one can boot without trouble. This is not the problem of Kaiten-yaki.
|
|
|
|
# Variants considerations
|
|
Ubuntu has several variants ( flavors ). While I have tested only MATE flavor, other flavor may work correctly as far as it uses Ubiquity installer.
|
|
|
|
# Acknowledgments
|
|
These scripts are based on the script shared on the [myn's diary](https://myn.hatenablog.jp/entry/install-ubuntu-focal-with-lvm-on-luks). That page contains rich information, hint and techniques around the encrypted volume and Ubiquity installer.
|
|
|
|
Also, following documents were very important to study how Void Linux installation works.
|
|
- [Full Disk Encryption](https://docs.voidlinux.org/installation/guides/fde.html) in the Void Handbook.
|
|
- [Install LVM LUKS](https://wiki.voidlinux.org/Install_LVM_LUKS) (deprecated)
