Install the utility in Rescue

Recovery and Diagnostic Mode Rescue contains pre-installed tools for system diagnostics and recovery.

If you need additional tools, install their packages through the package manager pacman.

Packages can be installed:

• from the official repository with additional tools Arch Linux;
• repository AUR In which users publish useful tools.

For your information

The tools are installed in RAM, so after a server reboot, all installed tools will be removed.

From the Arch Linux repository

1. Boot the server in Rescue and Diagnostic mode.

2. Mount the file system with the partition size extension cowspacedesigned for downloading packages:

   mount -t airootfs -o remount,size=4G /run/archiso/cowspace
