Install Utility in Rescue

Rescue recovery and diagnostics mode contains pre-installed tools for system diagnostics and recovery .

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

Packages can be installed:

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

warning

Tools are installed to RAM, so all installed tools will be deleted after the server reboots.

From the Arch Linux repository

1. Boot the server into Rescue recovery and diagnostics mode.

2. Mount the file system with the extended size of the cowspace partition intended for downloading packages:

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

3. Update the pacman package manager cache:

   pacman -Syy

4. Install the package:

   sudo pacman -S <package>

   Specify <package> — the package name. You can find the package name in the official Arch Linux repository.

From the AUR repository

An example of installing arcconf, a tool for managing a hardware RAID controller. You can install other tools from the AUR repository in the same way.

1. Boot the server into Rescue recovery and diagnostics mode.

2. Mount the file system with the extended size of the cowspace partition intended for downloading packages:

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

3. Install the base-devel package — a basic set of tools for further work with packages:

   sudo pacman -Syu base-devel

4. Install git:

   pacman -S git

5. Change to the directory for temporary file storage:

   cd /tmp

6. Clone the repository to install the package:

   git clone https://aur.archlinux.org/arcconf.git/

   Here, https://aur.archlinux.org/arcconf.git/ is the repository to clone. You can find it on the package page in the Git Clone URL line.

7. Go to the arcconf directory:

   cd arcconf

8. Switch to the branch with the latest commit.

   git checkout 98153da254e10bb2655ad1c7e0e118b2dd7fd18c

   Here, 98153da254e10bb2655ad1c7e0e118b2dd7fd18c is the commit ID. You can find it on the package page: click View PKGBUILD, open the commit tab, and check the value in the commit line.

9. Create a user user with permissions for the /tmp/arcconf directory:

   useradd -m user
   sudo chown -R user /tmp/arcconf
   sudo chmod -R 755 /tmp/arcconf

10. Switch to the user user:

    su user

11. Run the makepkg tool; it will check dependencies and build the package in the current directory:

    makepkg

12. View the directory content:

    ls

    A list of package files will appear in the response. For example:

    arcconf-4.17.00.26540-1-x86_64.pkg.tar.zst        arcconf_v3_07_23980.zip  src
    arcconf_B26540.zip                                pkg
    arcconf-debug-4.17.00.26540-1-x86_64.pkg.tar.zst  PKGBUILD

    Here, arcconf-4.17.00.26540-1-x86_64.pkg.tar.zst is the file name for installing the tool.

13. Copy the file name for installation.

14. Log out of the user user:

    exit

15. Install arcconf:

    pacman -U <file_name>

    Specify <file_name> — the file name you copied in step 13.
