Installing from a non-Calculate Linux

Updated 8 March 2019

This is about how to install Calculate Linux from an already running Linux host.

It may be useful for:

  • installing Calculate Linux wirelessly - for example, on a virtual server;
  • replacing your Linux system without a LiveCD;
  • creating a new Linux distribution or LiveCD, based on Calculate Linux.

It is simple, isn't it? Download the latest Calculate Linux release and save it to the / directory:

wget -P /

Please replace 20181005 with the relevant version. You can view version names here.

If you have a remote server, get a KVM console and then reboot the system. As on the figure below:


Once in Grub, hit "c" to go to the Grub command line and paste the following:

loopback loop /css-20181005-x86_64.iso
linux (loop)/boot/vmlinuz root=live iso-scan/filename=/css-20181005-x86_64.iso
initrd (loop)/boot/initrd

As on the figure as in:

Grub boot settings

The CL system image will then be loaded to RAM and launched. To start and install Calculate Scratch Server (in the example), 1Gb of RAM is enough.

You can install to the hard disk now:

cl-install -D /dev/vda --root-size=10G -l ru_RU --timezone Europe/Moscow --hostname

In the example above one 10 GB partition is created on the /dev/vda drive, defining your locale as fr_FR, your timezone as Europe/Paris and the network name of your computer as
