Can SystemRescue Be Installed on a Disk or Customized with Additional Software?

Yes. SystemRescue is designed to boot from a CD/DVD or USB stick without installation, but the project documentation also covers installing it on a hard disk, adding software packages with pacman, configuring it through YAML files, keeping your changes with a backing-store, and running your own scripts at start-up with autorun. These options are documented as advanced usage, so they assume you are already comfortable booting the toolkit and working from its command line.

Installing SystemRescue on the Disk

The default and simplest way to use SystemRescue is as a bootable medium: you write it to a USB stick or burn it to a disc and boot from that. The homepage states that no installation is required for this, but that the system can be installed on the hard disk if you wish.

Installing to disk makes sense when a machine is dedicated to rescue and maintenance work and you want the toolkit available without carrying a USB stick. The project documentation lists "Installing SystemRescue on the disk" as a separate advanced chapter, so treat it as a deliberate procedure rather than a quick copy: follow that chapter rather than improvising, because a disk install changes how the system boots and where its files live.

Adding Software with pacman

SystemRescue ships with a large set of Linux system utilities, including GParted, GNU Parted, FSArchiver, filesystem tools, editors, midnight commander, and network tools. If you need something beyond that set, the documentation covers "Installing additional software packages with pacman."

The practical constraint is persistence. A plain boot from read-only media starts fresh each time, so packages you install during one session are gone after reboot. To keep added software, combine pacman installs with the backing-store described below, or with a disk installation. The documentation treats these as related advanced topics for exactly this reason.

Keeping Changes with a Backing-Store

SystemRescue runs as a live system, so by default any configuration you change or software you add disappears when you shut down. The documented remedy is "Creating a backing-store to keep your modifications." A backing-store is a file that holds your changes so they survive reboots.

This is the option to choose when you want a customized rescue environment — your own tools, your network settings, your scripts — without committing a whole disk to SystemRescue. The trade-off is that the backing-store lives on some storage medium you must keep available and boot with; if that medium is missing or damaged, you are back to a default session.

Configuring with YAML Files and Autorun

Two further customization mechanisms are documented:

• YAML configuration files — "Configuring SystemRescue with YAML files" lets you define system settings in a structured file instead of changing them by hand each boot.
• Autorun scripts — "Run your own scripts at start-up with autorun" lets you execute custom commands automatically when the system starts, which is useful for repetitive setup tasks such as mounting specific partitions or starting network services.

Both are natural companions to a backing-store or disk install: the configuration and scripts persist, and the system applies them on every boot.

Choosing Between the Options

Where to Start

The homepage points to a Quick Start Guide for first-time users, and the advanced chapters above sit alongside it in the project documentation, together with guides on disk partitioning, LVM, networking, and backing up data from an unbootable Windows computer. If you are new to SystemRescue, boot it from a USB stick first and confirm the tools you need are present; only then decide whether a backing-store or a disk installation is worth setting up.
