What's this?†

FuguIta is the Live CD which was built from OpenBSD, featuring;

Similar to HDD installation
This Live CD was intended to be similar to HDD installation as much as possible.
After CD booting, you can login to the environment like the one which was just installed on HDD.
In this environment, many ordinary files have replaced to symbolic links. So you can replace or modify them by yourself.
Portable workplace
You can save your own environment into Floppy Disk and/or USB flash. Then you will be able to retrieve it at next boot time.
Low hardware requirements
Unless you will use X, this LiveCD requires 27MB of memory to run.
Additional Softwares
Some softwares were added from ports or building from other source packages. See following software list.
Useful for Japanese users
Kernel and Time Zone are set to JST. And some softwares are configured to be able to use Japanese.

Note: FuguIta (fuguita.gif) stands for "Blowfish Disk" in Japanese. Fugu means blowfish, and Ita means something flat such as a plate, a disk or a board etc...
Some Japanese might associate those who cook when hearing Ita. For them, so FuguIta also means a "Blowfish Cook".

How to use FuguIta†

↑

Download†

FuguIta is provided as compressed ISO images;

First, get via HTTP then make it uncompressed;

ftp http://kaw.ath.cx/dl/pub/OpenBSD/LiveCD/FuguIta-4.0-YYYYMMDDN.iso.bz2
bzip2 -d FuguIta-4.0-YYYYMMDDN.iso.bz2

or

ftp http://kaw.ath.cx/dl/pub/OpenBSD/LiveCD/FuguIta-4.0-YYYYMMDDN.iso.gz
gzip -d FuguIta-4.0-YYYYMMDDN.iso.gz

Note: ftp is a client for FTP/HTTP on OpenBSD. If you use other OS, use an appropriate HTTP client instead, such as fetch, wget, cURL or other web browsers.

↑

Burn CD-R†

Burn the ISO image into CD-R or CD-RW.

cdio -f /dev/rcd0c tao FuguIta-4.0-YYYYMMDDN.iso

Booting FuguIta†

After booting from CD, some user inputs will be prompted;

511 MB of memory available for you.
your mfs size in megabytes? [default: 255] ->

Only entering "ENTER", half amount of attached memory is specified by default.

Allocating 255 MB for mfs.

Choose the way of boot

Select boot method;
   0: CD-ROM only
   1: CD-ROM only (for low mem)
   2: CD-ROM + USB flash
   3: CD-ROM + tar.gz on floppy
   4: CD-ROM + interactive shell
-->0
0 CD-ROM only mode
Booting with CD-ROM only. Some parameters are needed to be entered manually.
1 CD-ROM only mode (for low mem)
Same as above.
But, under /usr are all read only.
2 CD-ROM + USB flash mode
After CD boot, extract files which were stored in USB flash. (to be more described)
3 CD-ROM + .tar.gz floppy mode
Same as above, but extracting from floppy disk. (to be more described)
4 CD-ROM + interactive shell mode
After CD boot, single user shell invoked. This is intended for system debug.

At first, you should enter mode 0 (recommended) or mode 1.

Tips†

Details will be written in future.

What can I do after boot?†

Almost same as normal installation on HDD.
See afterboot manual page by running man 8 afterboot.

↑

How to change TimeZone†

Re-link /etc/localtime;

cd /etc
ln -sf /usr/share/zoneinfo/YOUR-TIME-ZONE localtime

Then set system clock if nessesary;

date YOUR-LOCAL-TIME

Caution: date command causes your hardware clock changed.

Saving and restoring the modified files†

You can save your own environment into Floppy Disk and/or USB flash.
Note: Existing data on these media will be lost. You *MUST* back up your data before this operation.

To save in USB flash.

  1. Do fdisk 
    # fdisk -e sd0
    If your fdisk cannot get disk geometry info from USB-BIOS, make sure the size of your USB flash from dmesg output.
    For example, you know your USB flash has 248MB according to dmsg, you can fdisk with options specifying Cyl/Head/Sec explicitly. 
    # fdisk -c 248 -h 64 -s 16 -e sd0
    In fdisk editor mode, you will specify OpenBSD FFS as the partition ID ``A6''.
  2. Make then partition ``a'' by disklabel. 
    # disklabel -E sd0
    The procedure is normal. Refer disklabel(8).
  3. Format sd0a 
    # newfs -b 4096 -f 512 -i 1024 /dev/rsd0a
  4. Make the directory which saves the data. 
    # mount /dev/sd0a /mnt
# mkdir /mnt/livecd-config
# umount /dev/sd0a
  5. Save data.
    1. To save data, the script ``usbfadm'' are in the system. 
      # /boottmp/usbfadm
Welcome to USB flash maintenance tool.

Boot mode: manual

Type ? for help.

?:? ->
    2. Detect USB device by rescan subcommand. 
         ?:? -> rescan
   Rescanning USB flash
   Please make sure the device inserted.
   Then press ENTER -->

   USB flash memory found as sd0
    3. Name the set of data which you will save by dsn (data set name) subcommand. The default value of dsn is the FQDN of this host. 
      /dev/sd0a:? -> dsn

Enter data set name [nimbus5.localnet] -> emgproxy

Now data set name is set to ``emgproxy''.
    4. Save the data by sync subcommand. 
      /dev/sd0a:emgproxy -> sync

Sync current mfs as emgproxy, OK? -> y

Adding other softwares†

Usual way as in HDD installation.
Packages and ports are also OK.

Can I rebuild my own CD-ROM image?†

Yes.
Here's a brief description of how to build a LiveCD image;

  1. Get a build tool. 
    ftp http://kaw.ath.cx/dl/pub/OpenBSD/LiveCD/tools/tools-4.0.tar.gz
  2. Extract it 
    tar xvzpf tools-4.0.tar.gz
  3. Copy kernel 
    cd tools-4.0
rm bsd.orig
cp bsd bsd.orig
    (Or compile your customized kernel using tools-4.0/lib/RDROOT, then copy it to tools-4.0/bsd)

  4. Copy your OpenBSD file-tree under tools-4.0/cdroot.dist
    For example; 
    cd cdroot.dist
(cd YOUR-OPENBSD-FILE-TREE && tar cpf - .) | tar xvpf -
  5. Make an ISO image 
    make livecd.iso
  6. Burn it. 
    cdio -f /dev/rcd0c blank             ( <- Only for CD-RW )
cdio -f /dev/rcd0c tao livecd.iso

That's all.

Can I install this LiveCD to HDD?†

Yes, brief description as follows;

  1. Install OpenBSD on your hard disk in usual way.
    • This is for preparing OpenBSD disk partition.
  2. Preserve kernel and /etc/fstab.
    • Not to overwrite by CD-ROM's contents
  3. Mount CDROM, then copy its contents to hard disk
    • Not to copy CD-ROM oriented files - /cdboot, /cdbr, /bsd, /rr_moved etc...
    • After copying completed, retrieve kernel and fstab which were initially installed.
  4. Reinstall boot loader
    • See installboot(8) manual page
