Wary Puppy is built from a "Puppy builder" system named Woof (http://bkhome.org/woof), which can build a Puppy Linux distribution from the binary packages of any other distro.More over this is Puppy Linux variant that targets support for older hardware, especially in the areas of video and analog modem dial-up. It is a bug-fix and minor upgrade of Wary 5.0. The default kernel is now the long-term supported 2.6.32.28. The PET package repository is still small but is growing, with many major applications added to it. For a 'minor upgrade', rather a lot of applications have been upgraded, as well as one new one, the 'Wcpufreq' CPU frequency scaling tool, added. There have been numerous tweaks in the underlying infrastructure.

About Puppy Linux

Puppy Linux is yet another Linux distribution. What's different here is that Puppy is extraordinarily small, yet quite full-featured. Puppy boots into a ramdisk and, unlike live CD distributions that have to keep pulling stuff off the CD, it loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly. Puppy Linux has the ability to boot off a flash card or any USB memory device, CDROM, Zip disk or LS/120/240 Superdisk, floppy disks, internal hard drive. It can even use a multisession formatted CD-RW/DVD-RW to save everything back to the CD/DVD with no hard drive required at all.
