Not what I mean. My symlinks persist between the actual adapter being
connected. They do not persist between reboots. This was explained to me
on the macosx-talk list. Mac OS X uses devfs, and so the /dev/ directory
is recreated on each startup. Apparently, under linux, you can edit a
configuration file to add new devs ( and presumably symlinks ) when the
/dev/ directory is built, but the poster was unsure whether that would
work with Apple's implementation of devfs.
