Hi i have decided to open this thread about usb bootable distros. I want somehelp to understand why a peristent installation dont let u use the partition the distro is installed ? Why i should always have 2 partitions on my flash drive?
USB persistent installations store their filesystem in a file (and not a partition); that file (casper-rw) is later accessed when you boot into a USB session and is read as a filesystem. That's why you can't access is. You can think of it somewhat like a swap file generated during hibernation and stores a snapshot of virtual memory. So when you create a USB disk and allocate space for storing files, that space is pre-allocated.
Yes, you can definitely fit an Xfce distro on a 2 GB USB disk. Xfce is a very light desktop environment. (In fact, on a 2 GB drive you can even install GNOME / KDE distros).
