Because Fedora is using udev to control device entries, devices and
symlinks that you create yourself do not survive a reboot. This is
because /dev is a memory file system, not a real directory on the
hard drive, once udev is started. (Sort of like the /proc file
system. "/dev /dev tmpfs rw 0 0")

The way to get lasting symlinks is to create a udev rule for it. I
probably create a file in /etc/udev/rules.d/55-palm.rules for the rules.
