This page explains the differences between Frugal and Full installation.
BaseSFS to a drive partition with a chosen file system. All subsequent software installations, file edits and additions are saved in this file system. The directory structure is stored as viewed in a file window or listed by a terminal emulator.
When first run:
- the Puppy Linux loads the BaseSFS (also known as PupSfs) a Sfs file containing Linux file system and directory structure (RootFS) (read only) eg. lupu_528.sfs
- the Puppy 'save file' containing settings, additional software, modifications etc. (read/write) eg. lupusave-mysave.2fs
- additional software Sfs files (read only) eg. Gimp_2.7.3_528.sfs
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 file window or listed by a terminal emulator is actually contained within these compressed files.
