Puppy Universal Installer ext4 bug
Because syslinux or extlinux is not working with puppy linux for ext4 filesystem on the USB flash key Puppy USB Installer does not work with ext4 filesystem. I was disappointed after trying several times with Precise Puppy 5.4.3. Though the workaround is to use another Linux but I think puppy should fix it. I mentioned it on my blog post with some details as well. It would be so nice to see that Puppy Universal USB Installer works with ext4.
