Pre-1.0.7 users can use it by renaming it to usr_more.sfs
1.0.7 users can do the following
edit your ##rc.local## to add the following lines:-
if you are multiple .sfs files the increase then use the next /dev/loop that is empty i.e. the next usr*.sfs will go in /dev/loop6. If you run out of loops make new ones using mknod command as show above.
compressed __read-only__ file systems
Explanation of the Squash file system: [[http://tree.celinuxforum.org/CelfPubWiki/ELCEurope2008Presentations?action=AttachFile&do=get&target=squashfs-elce.pdf PDF]]
Puppy can make use of programs that have been [[http://puppylinux.org/wikka/software packaged in the SFS format]] which consist of a single file with the file extension //.sfs//
==Using SFS software packages within Puppy==
- 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 > [[http://www.murga-linux.com/puppy/viewtopic.php?p=490716#490716 SFS-Load]]//
- soon [[http://bkhome.org/blog/?viewDetailed=02202 another option]] will be available
- accessed through either the //Menu// or the command-line interface (and not by clicking on the SFS package file)

===How to make a SFS file of a software package===
Copy or move all the directories and files that make up the software package into one single directory. Then issue the //mksquashfs// command: %%
SYNTAX:mksquashfs source1 source2 ... dest [options] [-e list of exclude dirs/files]
mksquashfs <path_to_directory> <path_to_directory>.sfs -noappend
Verify the installed version of //mksquashfs// with:

"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.
01micko writes "I made a tool (see my signature) that makes it super easy for anyone to make a pet or sfs out of debs, if you want you can try it and maybe suggest where I can make improvements. debs2pkg or alien2puppy, the former is what it says and the latter supports Slack tgz and txz formats."
