network reconriguring by gennetconfs

kaw? (2018-08-07 (Tue) 18:18:25)

At FuguIta-6.3-201808061, a new tool called gennetconfs has been introduced.
This tool generates configuration files for networking, so you can reconfigure network settings;

synopsis
gennetconfs [dir]

dir is the directory which configuration files will generated on.
If dir not specified, current directory will be taken by default.
So,

gennetconfs /etc

will overwrite directly existing files under /etc .

Because of gennetconfs was derived from FuguIta's boot sequence /boottmp/rc,
the interaction with gennetconfs is the same as one at boot time.


Various Operations of FuguIta

kaw? (2018-06-04 (Mon) 15:23:16)

FuguIta originally started as a LiveCD, but now we can use various devices. In addition, there are several types in operation.
So, I tried to make a table of combinations of how these devices can be used.
Note that If there are multiple available devices, you can use them in combination.

Explanation of the table

In the table above, each column indicates a device that FuguIta can handle.

CD (distrib. ISO)
CD, CD-R, CD-RW etc burned ISO image downloaded from distribution site.
You can burn it to DVD but you can use it, the size is 700 MB same as CD.
USB (distrib. img)
This is a USB flashdrive into which the IMG file downloaded from the distribution site is written.
Regardless of the USB flashdrive size used, the capacity is fixed at 1 GB (system 700 MB + data storage area 300 MB).
USB (usbfadm)
This is a USB flashdrive created using FuguIta's usbfadm command.
When executing the usbfadm command, you can set the size of the data storage area.
You can also create FAT in free space not used by FuguIta for data exchange with other OS.
OpenBSD
OpenBSD system already installed. To use this from FuguIta, perform the following operations in advance.
  • a : Copy FuguIta's kernel - /sysmedia/bsd-fi and /sysmedia/bsd-fi.mp to the partition where the OpenBSD kernel resides, and by entering "bsd-fi.mp" or "bsd-fi" for boot prompt "boot>", FuguIta starts up.
  • b : By creating a directory called "ISO" on any partition of OpenBSD and placing the ISO image of FuguIta here, you can use it as an operational device.
  • c : You can save and restore data here by creating a directory called "livecd-config" on any partition of OpenBSD.
    However, you can not do b and c at the same time on the same partition.
SD (usbfadm)
This is an SD card created using FuguIta usbfadm command.
ExtFS/NTFS/FAT
Linux ext2fs ... ext4fs and Windows NTFS, FAT partitions.
By creating a directory called "ISO" on these partitions and placing the FuguIta ISO image here, you can use it as an operational device.
tmpfs
File system created in memory. It is created automatically when FuguIta is started, and the contents are lost at the end.

Each line of the table is an operation form which can be selected at the time of starting up FuguIta or during operation.

boot from
FuguIta is a bootable device that loads the kernel. If there are multiple bootable devices, specify them using the BIOS boot menu.
run on
This is the device where the system file of Fugu Ita is installed and used for operation. It is mounted read-only.
If there are multiple available devices, specify the device at startup.
with boot mode
This is how to layout memory and operation devices during operation. The main boot modes are as follows.
  • mode 0 : This is standard operation as LiveCD / LiveUSB.
  • mode 1 : It is almost the same as mode 0, but it is completed in a shorter time and it operates with saving memory (about 64 MB minimum). However, pkg_add cannot be used because /usr becomes non-writable.
  • mode 2 : It operates using only tmpfs. Although it takes time to complete the boot, file input/output during operation is fast. Memory requires about 800 MB, or more.
  • mode 3 : Read data saved by usbfadm at boot time.
set parameters with
Usually, when starting FuguIta, it is necessary to manually input the operation device, tmpfs size, start mode, etc. However, if these parameters are described in the file "noasks", at startup this is set automatically, you can omit manual input.
save data to
As described in boot mode 3, you can save the file to the device specified by the usbfadm command.

FuguIta 6.3 for Raspberry Pi 3

kaw? (2018-05-31 (Thu) 16:42:17)

Although it is still a test version, it is working well on my RPi3.
Even without a serial cable, you can install and use it by connecting from the SSH client.

README for more further details.
