Overview

SFS extensions can be installed on flash drive, frugal and full installations. However, the SFS extensions support of full installations is limited: they must be installed manually and cannot be uninstalled.

Under flash drive and frugal installations, the installation and uninstallation of SFS extensions is easy and convenient.

To install a SFS extension, put it in the root of /mnt/home first (the partition where pup-xxx.sfs, vmlinuz and initrd.gz are). For instance, I wish to install the go-oo-3.2-sfs4.sfs (an OpenOffice extension) and my Puppy is booted from /dev/sda5. I downloaded the SFS extension and placed it in /mnt/home.

Bear in mind that SFS extensions can be put anywhere; you can place links to them in /mnt/home. This way, you sort extensions by their type or name and place them in different directories, for easier maintenance. Remember, this doesn't apply to all flash drive installations, as some flash drives are formatted to FAT16 or FAT32, which aren't Linux file systems and therefore do not support links.

To make Puppy mount your SFS extension when it boots, start the Boot Configuration panel, through the “System” menu.

Then, go to the SFS files manager.

A window with 2 lists will appear: the left one lists the SFS extension in /mnt/home, while the right one lists the ones to mount on boot.

Select your SFS extension on the left list and click “Add” to make Puppy mount it each time it boots.

Now, click “OK” to apply the changes and reboot.

To uninstall a SFS extension, go to the Boot Configuration panel and do the same, but this time, select it on the right list and click “Remove” instead. Then, you can delete your SFS extension from /mnt/home.

Under full installations, SFS extensions must be extracted in order to be installed. There is an automatic SFS installer, but it is always good to know the manual way of doing things. In this example, I installed centerim-4.22.9-sfs4.sfs (a CenterIM extension).

First of all, click the SFS extension in order to mount it.

Then, select all the files and directories inside them and copy them to /. Let ROX-Filer replace existing files and merge directories.
