Frugal or Full Installation
This page explains the differences between InstallationFrugal Frugal and InstallationFullHDD Full installation.
Full Installation
In a Full installation the 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
A frugal installation involves using compressed 'filesystem-within-a-file/s' without expanding them. These files are,When first run:
- the Puppy Linux loads the BaseSFS (also known as PupSfs) a SquashFS Sfs file containing Linux file system and directory structure (RootFS) (read only) eg. lupu_528.sfs
Additional files:
- the Puppy SaveFile 'save file' containing settings, additional software, modifications etc. (read/write) eg. lupusave-mysave.2fs
- additional software SquashFS 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 FileManagers file manager or listed by a TerminalEmulater terminal emulator is actually contained within these compressed files.

Comparsion
| Full | Frugal (not in RAM) | Frugal (copied to RAM) | |
|---|---|---|---|
| Drive partition required | Yes | No | No |
| Installation directory | Requires a drive partition | Almost any directory | Almost any directory |
| Speed | Medium | Likely to be slower | Faster |
| Installation file system | Linux Type | FAT, NTFS, Linux Type | FAT, NTFS, Linux Type |
| Installation Protection | RootFS writable with root user access | BaseSfs Read only | BaseSfs Read only |
| SaveFile Pup SaveFile | No, directly accesses RootFS | Yes, saved directly to disk | Yes, in RAM (saved to disk on request/reboot) |
| Load/Unload SquashFS SFS files | Harder | Easy | Easy |
