In this page, we will explain the simple usage of FuguIta.
FuguIta provides ISO images for LiveDVD and raw disk image files for LiveUSB and others for i386 and amd64 platforms and arm64 (Raspberry Pi 3/4) respectively.
To obtain the FuguIta file, select the appropriate mirror site from the list, then download it from there. Here is an example on OpenBSD.
# ftp http://MIRROR.dl.fuguita.org/MEDIA/FuguIta-X.X-ARCH-YYYYMMDDN.TYPE.gz # ftp http://MIRROR.dl.fuguita.org/MEDIA/SHA256
In the example above, note that the part of MIRROR, MEDIA, X.X, ARCH, YYYYMMDDN and TYPE must be replaced by the actual names.
Note: Unlike many Linux distributions and others, ISO images (*.iso.gz files) cannot be used for LiveUSB, only LiveDVD.
To create a LiveUSB, use the raw disk image (*.img.gz file).
SHA256 is a checksum file to check the integrity of the downloaded FuguIta file.
After the download is complete, please make sure that the file is not corrupted.
sha256 -C SHA256 FuguIta-X.X-ARCH-YYYYMMDDN.TYPE.gz
OpenBSD itself does not include software for burning DVDs. So install dvd+rw-tools to burn DVD from packages.
- Install DVD writing tool
# pkg_add dvd+rw-tools- Decompress the ISO file, then burn that image into DVD-R or DVD-RW.
# gzip -d FuguIta-X.X-ARCH-YYYYMMDDN.iso.gz # dvd-rw-format /dev/rcd0c (format media, if you will be burn it first) # growisofs --dvd-compat -Z /dev/rcd0c=FuguIta-X.X-ARCH-YYYYMMDDN.iso
To make a 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. The following is an example of writing using OpenBSD.
- Decompress that image, and write it into USB storage device.
# gzip -dc FuguIta-X.X-ARCH-YYYYMMDDN.img.gz | dd of=/dev/rsd?c bs=1mThe /dev/rsd?c part in the above example is the designation of the write destination device. This depends on the connection status of the peripherals of your PC. If you execute this command, all the data recorded in the specified device will be erased, so be sure to check in advance if the write destination is correct.
If you are not sure what device to write, run the following command to check the name of the device before writing.# tail -f /var/log/messages # Insert USB flashdrive after this command Jun 12 09:59:30 fugu-demo /bsd: inteldrm0: 1280x800, 32bpp Jun 12 09:59:30 fugu-demo /bsd: wsdisplay0 at inteldrm0 mux 1: console (std, vt1 00 emulation), using wskbd0 Jun 12 09:59:30 fugu-demo /bsd: wskbd1: connecting to wsdisplay0 Jun 12 09:59:30 fugu-demo /bsd: wsdisplay0: screen 1-5 added (std, vt100 emulati on) Jun 12 09:59:30 fugu-demo slaacd[37947]: sendmsg: Can't assign requested address Jun 12 09:59:30 fugu-demo ntpd[67052]: creating new /var/db/ntpd.drift Jun 12 09:59:31 fugu-demo savecore: can't find device 17/1 Jun 12 10:00:02 fugu-demo syslogd[50034]: restart Jun 12 10:00:50 fugu-demo /bsd: umass1 at uhub4 port 3 configuration 1 interface # Following lines will 0 "UFD 3.0 Silicon-Power32G" rev 2.10/0.0c addr 9 # appear after tail Jun 12 10:00:50 fugu-demo /bsd: umass1: using SCSI over Bulk-Only # command was executed.

The "r" in the device name means "raw device" and the "c" represents the entire device.
This is the same as Creating LiveUSB.
Write FuguIta's raw disk file to micro SD device in a same way.
After displaying FuguIta's logo, selection of FuguIta's operational device will appear.
Unless you attached multiple FuguIta devices, simply press ENTER key (accepting default value) is OK.

Which is FuguIta's operating device? [default: cd0a] ->
The next step is to configure settings related to memory.
In the example below, it is first reported that 1007 megabytes of memory is available for this PC. The user then enters how many megabytes of that 1007MB of memory will be allocated to mfs.
The default value is shown as "default: 755M" in the entry field, and this value is assumed to be specified when only the <Enter> key is pressed. Normally, you only need to press <Enter> to enter the value.
activating swap partition: /dev/sd0b available memory: 1007M total swap size: 16M Enter mfs size. You can add suffix K, M, or G. % is a percentage of memory size. and %% is a percentage of the total memory and swap. otherwise considered "megabytes" [default: 755M] -> <== Press only <Enter> here set mfs size to 755MB
Select boot mode.
At first boot, we recommend mode 0.
Boot modes:
0: fresh boot - standard mode as a live system
1: fresh boot - less memory, faster boot (/usr is non-writable, can't pkg_add)
2: fresh boot - works using only RAM (about 1GB or more of RAM required)
3: boot with retrieving saved files from storage device
or enter passphrase for an encrypted volume
4: boot with retrieving saved files from floppy disk
5: interactive shell for debugging

New password: Retype new password:
Entering the Host Name
Enter the host name with domain (FQDN: Fully Qualified Domain Name). You can omit the domain part if you do not need it, for example, when using it in a closed network.
Hostname with domain part (FQDN): only host name without domain part is also OK. -> fugu-demo.localnet
which IP protocol version to enable
The default is "64" (enable both IPv6 and IPv4, but give priority to IPv6 for name resolution).
IP protocol version(s) to be enabled: 4, 6, 46, 64 or "none" 4: enable only IPv4 6: enable only IPv6 46: give priority to IPv4 name resolution 64: give priority to IPv6 name resolution none: operate as standalone [64] ->
If "none" is specified, the device will operate as a standalone device that does not use the network, and network-related configuration will be completed.
Specifying the network interface
Next, a list of network devices will be displayed, and you need to specify only one device that you want to configure.
Network Interfaces: Choose one
NIC type Name
-------- ----- ------------
bge1 ether Broadcom BCM57766
ure0 ether Realtek USB 10/100/1000 LAN
run0 wifi Ralink 802.11 n WLAN
[bge1] ->
The device that appears at the top of the list will be the default. If you specify a Wi-Fi device, you will be prompted to enter the SSID and encryption key.
[bge1] -> run0 Wi-Fi settings: SSID -> OUR-WIFI-NETWORK WPA Key -> OUR-WIFI-SECRET
If you press only ENTER with the WPA key, you will be prompted to enter WEP.
WPA Key -> WEP Key -> OUR-WEP-SECRET
If you press only ENTER with the WEP key, it means that you specify the connection without encryption.
IPv6 Settings
If you have enabled IPv6, the following configuration input will appear. Set the address to "auto" or manually, as described in the description. In most cases, "auto" will work. If "/prefixlen" is omitted, it is assumed that "/64" is specified.
IPv6 - address and routing: Enter "auto" or "IPv6_address[/prefixlen] [default_gateway]" "auto" is an automatic setting by SLAAC. The "/prefixlen" part can be an integer between 0 and 128. If there is no default gateway, set the second field to "none" or leave it blank. [auto] ->
5. IPv4 Settings
If you have enabled IPv4, you will be prompted to enter the following settings: "auto" for DHCP, as described in the description; otherwise, set the address manually.
If you omit "/mask", a netmask that seems appropriate will be assumed.
IPv4 - address and routing: Enter "auto" or "IPv4_address[/mask] [default_gateway]" "auto" is an automatic setting by DHCP. The "/mask" part can be specified in either format, such as "/255.255.255.0" or "/24". If there is no default gateway, set the second field to "none" or leave it blank. [auto] -> 192.168.1.147/24 192.168.1.254
6. DNS Server Settings
If you have configured IPv4 or IPv6 addresses manually, you will be prompted to enter DNS server settings. If you want to communicate directly by specifying IP addresses, you do not need to use DNS servers, so enter only ENTER.
DNS servers: up to 3 IP addresses, separated by spaces -> 192.168.1.253
Finally, configuration files reflecting the configuration values you have entered will be written to the directory "/etc/fuguita/netconfs/config_name".
writing configured values to: /etc/fuguita/netconfs/default/myname /etc/fuguita/netconfs/default/mygate /etc/fuguita/netconfs/default/hosts /etc/fuguita/netconfs/default/hostname.bge1 /etc/fuguita/netconfs/default/resolv.conf
If you wish to use X Window System, type X.
Do you login with C)onsole or X) Window System?
[default: C] ->

FuguIta will make the minimum settings necessary for the operation of the OS at boot time. In addition, you should configure the environment for running applications after root login as shown in the example below:
As explained in "Creating LiveUSB", you can create a Fuguita LiveUSB by downloading the image file from the download site, extracting it, and writing to it.
However, regardless of the size of the USB flash drive, the LiveUSB version of the FuguIta can only use 2GB of space. Of this, the FuguIta system occupies about 1GB, so the usbfadm can only store about 1GB of data.
The usbfadm utility that comes with the FuguIta has a function called expand that allows you to expand the size of a specified partition. An example of using expand is shown below.

Select the expansion method for sd1d:

There are two ways to expand a partition: "growfs" and "newfs".
With growfs, the area is expanded while retaining the data stored in the partition.
With newfs, the partition is extended and then reformatted.
So, all files and directories stored on the partition will be lost.
Since there is no data stored on it now, we will choose newfs.
This makes sd1d as large as possible.
Note that all contents in sd1d will be removed

If you said YES at setup of Japanese Environment of dtjsetup, you do not need to do this.
In OpenBSD, the command doas is used to temporarily perform work as a system administrator.
By setting the contents of the doas configuration file /etc/doas.conf as follows, users belonging to the wheel group can perform system management tasks.
# echo permit persist :wheel > /etc/doas.conf
If you wish add application softwares more, ports/packages system can be used as usual.
Please refer OpenBSD's FAQ for detailed info.
To create an normal user, use adduser utility as follows:

OpenBSD/amd64 (fugu-demo.localnet) (tty00)
login:
Note: Even if you are using FuguIta Live DVD, it is possible to save the data and load them at the next boot if LiveUSB is also attached.
FuguIta prompts the user to enter the following 5 items at boot time:
You can automate those inputs by editing the noasks files in the d partition of your LiveUSB system (in case of OpenBSD/amd64).
# mount /dev/sd0d /mnt # vi /mnt/livecd-config/7.0/amd64/noasks
Edit noasks file to fill item values and to uncomment them
# # noasks - parameter settings for non-interactive boot # # Make statements uncommented # to activate settings # # # FuguIta system device noask_rdev=sd0a # # mfs size in MB noask_umem=0 # # boot mode noask_setup_rw_mode=3 # # storage device noask_confdev=sd0d # # data set name in USB flash drive noask_confdir=fugu-demo
# umount /mnt
Since noasks edited, following line will appear at boot time:
# reboot ...snip... ============================================ = ______ __ _ = / ____/ | |_| |__ = / /____ ______ __ _| /_ _/_____ = / ___/ / / / __ \/ / / | | | | / _ | = / / / /_/ / /_/ / /_/ /| | | |_| (_) |__ =/_/ \____/\__ /\____/ |__| \___/____/__/ = __/ / = /___/ = = Welcome to FuguIta! - OpenBSD Live System = http://fuguita.org/?FuguIta ============================================= scanning partitions: wd0i wd0j sd0a sd0d sd0i FuguIta's operating device(s): sd0a. Press ^C to cancel non-interactive boot
Wait 5 seconds after this message is displayed, and the boot will be continued without any user interaction. If you enter <Control>-C within 5 seconds, the automatic boot by the noasks file will be stopped and the normal manual operation will be restored.
In the previous section, making it possible to omit entering configuration settings at startup, we discussed automating the startup of FuguIta, and it is also possible to save data automatically at shutdown.
OpenBSD runs a script called /etc/rc.shutdown when the system shutdown. On FuguIta, the data saving process is described in /etc/rc.shutdown.
force_umount=No # set Yes for forced umount /ram at shutdown force_resync=No # set Yes to re-sync at shutdown ...snip...
If force_resync is set to Yes, data will be saved at shutdown.
Note: Although this process provides error recovery in case the save process fails. However, it is not safe in all cases. If you perform important operations during operation, we recommend that you manually save the data separately before shutting down.
FuguIta can be used in various ways by combining boot modes and media. See the FuguIta Guide for such applications. The FuguIta Guide is the comprehensive document.
