Frugal or Full Installation

This page explains the differences between Frugal and InstallationFullHDD Full installation.

Full Installation
In a Full installation the system files (Linux directory structure) takes up a whole drive partition. The contents from Puppy Linux's BaseSFS are extracted to the linux directory structure. All subsequent software installations, file edits and additions are made directly to the partition's file system. The directory structure is stored as it appears in the FileManagers file manager or listed by a TerminalEmulator terminal emulator.

Frugal Installation
In a Frugal installation the system files (Linux directory structure) are compressed into a couple of file (technically filesystems within a file):


When first run:


Additional files:


On start-up these file-systems are super-imposed upon each other so that they appear merged. Additional files and alterations are written to the Puppy Save File (if within the Linux directory structure). The directory structure viewed in a FileManagers file manager or listed by a TerminalEmulator terminal emulator is actually contained within these compressed files.
