LiveDVD and LiveUSB†

There are two main ways to use FuguIta.

One is a method called "LiveDVD" that writes FuguIta to a DVD-R or DVD-RW and starts it.
The other method is to boot what is written in the USB memory, which is called "LiveUSB".

FuguIta can be used in the same way by using either the LiveDVD version or the LiveUSB version, but each has its own characteristics, so it is better to use them according to the purpose.

In general, USB memory has a faster data reading speed than DVD, so the LiveUSB version of FuguIta often takes less time to complete system and application startup.

Some old PCs can't boot from USB sticks well or don't support booting itself.
On the other hand, most DVD drives are manufactured according to standardized specifications, so FuguIta will start up with almost all of them without any problems.

FuguIta and other "live systems" are not installed on a hard disk, so all data is held in memory. For this reason, normally all data up to that point will be lost when the system is shut down.
The LiveUSB version of FuguIta has a data storage area, and you can save various settings and files in this area and restore them at the next system startup.

The unit price of recording media is cheaper for optical media such as DVD-R than USB memory, so you can run it on multiple machines at the same time, use the media while it is set, or create in large quantities. The LiveDVD version is more suitable for usage such as distributing

In general, it can be said that the LiveDVD version is suitable for reliable operation and economic efficiency, and the LiveUSB version is suitable for performance and convenience.

[Memo]
⇒Using both the LiveDVD version and the LiveUSB version at the same time You can also use it in a "best of the best" way.
Using this technique, you can, for example, "use the LiveUSB version of FuguIta on a PC that does not support USB boot" or "save and read data with the LiveDVD version of FuguIta".

To get started with FuguIta for the first time, follow these steps:

Download files from FuguIta's distribution site
The downloaded file is compressed, so expand it
Write expanded files to DVD-R or USB memory

Each step is described below.

Download†

FuguIta is free software. All versions of FuguIta, including the latest version, are published on the Internet and can be freely downloaded and used.

There are four download sites for FuguIta.

https://jp1.dl.fuguita.org/

https://jp2.dl.fuguita.org/

https://de.dl.fuguita.org/

https://fr.dl.fuguita.org/

Since the content of the site is the same, you can download from either site in the same way.
From Japan, we recommend downloading from jp1.dl.fuguita.org or jp2.dl.fuguita.org.

When you visit these sites, you will see something like the image on the right. Among these, files with names starting with "FuguIta-" are FuguIta distributions.

The meaning of this file name is as follows.

FuguIta-7.2-amd64-202302031.iso.gz
        --- ----- --------- --- --+->file compression format
         |    |       |      |       ・gz ... compressed with gzip
         |    |       |      +->type of file
         |    |       |         ・iso ... ISO image for DVD-R/DVD-RW writing
         |    |       |         ・img ... Raw image for USB memory writing
         |    |       |
         |    |       +->Version of FuguIta
         |    |          ・It is in the format of "date" and "serial number"
         |    |          ・The serial number will be incremented by one
         |    |            if created more than one FuguIta in one day.
         |    |
         |    +->Compatible platform
         |       FuguIta currently supports 3 platforms: i386, amd64, and arm64.
         |        Please select the one that corresponds to the CPU model of your PC.
         |
         +->The version of OpenBSD that this FuguIta is based on

Select and download files based on whether you want to create a LiveDVD or LiveUSB, or whether your PC has an Intel 32-bit CPU or 64-bit CPU.

[Note: Supported architectures]
⇒ As explained above, when using FuguIta on a PC, it is necessary to select either i386 or amd64 depending on the type of CPU, but most PCs currently in use are amd64 Architecture 64-bit CPU. i386 is a 32-bit CPU that was developed before amd64.
arm64 is a CPU architecture commonly used in single board computers. The arm64 version of FuguIta has been confirmed to work on Raspberry Pi 3 and 4.

After the download is complete, extract the compressed file.
The following is an example of extracting files for DVD-R/DVD-RW from the shell command line on Unix OS;

gzip -d FuguIta-7.2-amd64-202302031.iso.gz

When the expansion is completed, the file size will be about 1 gigabyte, and the file name will also have the .gz extension.

[Memo]
⇒file SHA256 contains the SHA256 checksum of FuguIta's files and can be used to check if the downloaded file is corrupted.
To check, also download the SHA256 file and do the following:
sha256 -C SHA256 FuguIta-7.2-amd64-202302031.iso.gz
This is an example done on OpenBSD. For other OS, please refer to their respective manuals.

Create LiveDVD†

To create the LiveDVD version of FuguIta, prepare a writable DVD media such as DVD-R or DVD-RW, and write the expanded ISO format file.
Here is an example when writing on OpenBSD;

pkg_add dvd+rw-tools                                                  ←Install DVD writing software dvd+rw-tools
growisofs --dvd-compat -Z /dev/rcd0c=FuguIta-7.2-amd64-202302031.iso  ←Write image

[Memo]
⇒For other OS ISO image writing software is available so you can use such software to create FuguIta's LiveDVD .

↑

Create LiveUSB†

To create the LiveUSB version of FuguIta, prepare a USB memory with a size of 2 gigabytes or more, and write the downloaded and expanded IMG format file.
Here is an example when writing using OpenBSD;

dd if=FuguIta-7.2-amd64-202302031.img of=/dev/rsd0c

[Caution]
! ! The ``/dev/rsd0c'' part in the above example is the device to write to. This depends on your PC's peripheral connections, or the type of operating system you run the dd command on. If you execute this command, all the data recorded in the specified device will be erased, so please check in advance whether the write destination is correct.

[Memo]
⇒Similar to ISO image writing software, Various software for raw image writing is also available, so such software is available.
⇒ Even if you use a USB memory of 2 GB or more, the portion exceeding 2 GB is not used.
If you want to create a LiveUSB version of FuguIta that fits the size of the USB memory, please refer to LiveUSB remastering.
