What LCFG is

LCFG is a free, GPL-licensed system for automatically installing and managing configurations across large groups of Unix machines, particularly at sites with varied setups that change often. Administrators keep configuration source files on a central server; LCFG compiles them into XML profiles that client machines download when profiles change. Client components respond to resource changes by creating configuration files and reconfiguring associated daemons. A package component aligns each machine’s installed packages with its profile. New machines can be installed over a network file system, using a boot floppy or PXE after their source files have been created. LCFG is self-hosted and agent-based, with patch management. Its documentation covers system configuration, dynamic networking, and tools for developing components and software. The project lists Ubuntu 20.04, 22.04, and 24.04 as supported platforms. Its FAQ also names Fedora Core 3, 5, and 6 and Scientific Linux 5. The same FAQ describes Solaris as less supported and not packaged for distribution, the Mac OS X port as experimental and not production quality, and the demonstration Windows client as lacking real components. The project offers an archived mailing list and regular meetings open to users and prospective users.

Who it suits

LCFG may suit administrators at sites managing many Unix machines with varied, changing configurations. It is especially relevant where self-hosted, profile-based configuration and package management fit the operating environment.

What it does well

Freely available under the GPL.
Manages configurations through central XML profiles.
Synchronizes installed packages with machine profiles.
Supports network-based installation using PXE or a boot floppy.
Documentation covers dynamic network configuration.

What to know first

Solaris support is less complete and not packaged.
Mac OS X port is experimental.
Demonstration Windows client has no real components.
Listed Fedora releases are older versions.

Limits

LCFG is listed as free, with all software available under the GPL. The FAQ describes the Mac OS X port as experimental, Solaris as less well supported and not packaged for distribution, and the demonstration Windows client as having no real components.

Getting started

Visit https://www.lcfg.org/.
Review the system configuration guide and build tool documentation.
Prepare configuration source files for the machines on a central server.
Compile the source into XML profiles for client machines.
Install new machines over a network file system using a boot floppy or PXE.
Use the archived mailing list or attend a regular meeting for project discussion.

Verdict

LCFG provides a profile-driven way to configure and maintain large Unix environments, with package synchronization and network installation. Check its platform notes carefully, since support differs across operating systems.

Questions

How much does LCFG cost?

The LCFG plan is listed as free, and the software is freely available under the GPL.

Which platforms does LCFG support?

Listed supported platforms are Ubuntu 20.04, Ubuntu 22.04 and Ubuntu 24.04. The FAQ also names Fedora Core 3, 5 and 6 and Scientific Linux 5.

Can LCFG manage Windows or macOS systems?

The FAQ describes a demonstration Windows client that can retrieve profile resource values but has no real components. The Mac OS X port is experimental and not production quality.

How does LCFG apply configuration changes?

Administrators maintain source files centrally; LCFG compiles them into XML profiles that client machines download when profiles change. Client components then create configuration files and reconfigure associated daemons.

Can LCFG install new machines automatically?

Yes. After source files are created, new machines can boot from a network file system using a boot floppy or PXE.

Who created LCFG, and when?

LCFG was originally designed by Paul Anderson at the University of Edinburgh around 1993.
