read-only file systems
Explanation of the Squash file system: PDF
Puppy can make use of programs that have been packaged in the SFS format which consist of a single file with the file extension .sfs
- place the SFS file at /mnt/home, then
- either (A) follow the instructions at (requires re-booting): Menu > System > BootManager
- or (B) follow the instructions at (does not require re-booting): Menu > Setup > SFS-Load
- soon another option will be available
- accessed through either the Menu or the command-line interface (and not by clicking on the SFS package file)

Advantages of Squash file compression
"SFS-TCZ_Linker may be a good idea if you absolutely must run liveCD only (no rebooting, no session saving.) But running a standard frugal with pupsave, the Linker will add symlinks to the pupsave layer only--and later remove them, even if similarly named files or links were later added via PPM, Gslapt or other means. This is likely to adversely affect reliability and stability. With a full install any files removed would be gone forever, making it even riskier. So at least for now, if you are saving your session at shutdown I still recommend a frugal install and BootManager for adding SFS files."
Adding too many layers to AUFS reduces performance and slows down saving.
