Download and write the ISO

Which image

Two images are published, both live media, both carrying the installer:

Image Contents
obarun-<date>-x86_64.iso Minimal. Console system with the core tools and the 66 services needed to boot and recover.
obarun-JWM-<date>-x86_64.iso The same base plus a graphical session built around the JWM window manager.

Either image can install either system. The installer offers both themes whichever medium you booted from, so the choice of image only decides what the live environment looks like.

Images are built automatically on the first day of every month, so the version is simply the build date. A recent image means a shorter first update.

Where to get one

  • Latest image: web.obarun.org/download always points at the newest build.
  • A specific version: the releases page of the iso-builder repository keeps one release per image and per month, each with its checksum file.

Verify the image

Every build publishes an md5sums.txt next to its images. Download it, then check what you got:

$ md5sum -c md5sums.txt --ignore-missing

The line for your image must say OK. If it does not, download again. Writing a corrupt image produces a medium that fails in confusing ways much later.

Write it to a USB stick

Obarun images are directly bootable. No special tool is needed, and tools that "prepare" a stick for you usually break the image.

Identify the device first:

$ lsblk -o NAME,SIZE,TYPE,MOUNTPOINTS

Pick the whole device, /dev/sdx in the examples below, never a partition such as /dev/sdx1. Unmount anything mounted from it:

# umount /dev/sdx*

This destroys everything on the target device

dd does not ask for confirmation and does not check what it is writing over. Read the device name twice before pressing Enter.

# dd bs=4M if=obarun-<date>-x86_64.iso of=/dev/sdx status=progress oflag=sync

Wait for the command to return before unplugging the stick.

From Windows

Most Windows USB writers mangle the image and produce a medium that will not boot. Follow the Arch Wiki page on USB flash installation media, which lists the tools known to work.

Log in to the live system

The live media announce their credentials on the login screen:

Account Password
root toor
oblive toor

These are live-medium credentials only. They have nothing to do with the accounts you create during installation.
