If you didn't mount your F14 partition and chroot into it, it would
only update the F15 live session in memory and would be lost on
shutdown unless you added a persistent overlay when you setup your
live image (you didn't mention if it was live cd or live USB based).

Seeing as (with the above assumptions) all the updates will be lost on
shutdown, probably not worth it.
