From Fedora Project Wiki
- Bruno: One feature of liveusb installs is that the system is compressed. This allows you to run Fedora on a smaller USB drive than you would with a normal install. There are disadvantages to this as well in that the compressed system that is initially installed is read only. Updates are handled using an overlay file system. The initial packages still take up space after they have been updated and updates aren't compressed. So that you end up needing to update your liveusb with updated isos from time to time.
- Bruno: I think the data persistence issue is being over emphasized. USB drives are fairly reliable. I'd be more worried about losing one or doing something dumb with running it, than it wearing out.
- Bruno: If you download the isos and use livecd-iso-to-disk to make a liveusb there is good separation between the getting the iso step and putting a live iso on a usb step. This wouldn't be suitable for a lot of our target audience, but I think is easier than what the description of doing this via LiveMedia suggested.
- Bruno: I think the constrained package set is both an advantage and a disadvantage. The full install allows you to use the same media to do somewhat different installs, which can be useful if you have limited space or other reasons for not wanting to install everything that is on the media.
