Processor (CPU)
Debian From Scratch (DFS) requires a processor that supports PAE (Physical Address Extension)—this includes both 32-bit and 64-bit CPUs. For basic desktop use, a single-core processor may suffice, but compiling large software packages (like the Linux kernel or desktop environments) or running multi-tasking workloads (e.g., servers) benefits significantly from multi-core processors, which improve compilation speed and system responsiveness.
Memory (RAM)
The minimum RAM requirement for DFS is 1GB for basic desktop usage. However, if you plan to compile large components (such as the kernel or system libraries) or use graphics-intensive applications, 4GB or more of RAM is strongly recommended. Compilation processes consume substantial memory, and insufficient RAM can lead to slow performance or failures during the build steps.
Hard Disk Space
A minimum of 10GB of available disk space is required to install the basic Debian system. For a functional desktop environment with additional applications (e.g., office suites, web browsers) or for storing personal data, 20GB or more is advisable. During the build process, temporary files (from compiling source code) can take up significant space, so extra storage helps avoid interruptions.
Graphics Card
DFS is compatible with most modern graphics cards, including those from Intel (HD Graphics series), AMD (Radeon series), and NVIDIA (GeForce series). A compatible GPU is necessary for supporting graphical user interfaces (GUIs) like GNOME or KDE, as well as for hardware-accelerated tasks (e.g., video playback, 3D rendering). Basic integrated graphics (e.g., Intel HD 4000) are sufficient for standard desktop use.
