Does anyone know what the potential problems associated with symlinks
to devices are, I seem to recall that there are some, but can't recall
what (exactly) they are. I just mention this so we make sure to
consider it before making policy.
Is it just the lockfile naming issue? If so, then I suppose if
*every* program respected the symlink, and didn't do an end run to the
actual device, we'd be OK, but it still makes me a little nervous.
Not that I like the alternative of having to modify every script that
references the modem device whenever you change serial ports (say from
ttyS0 to ttyS1) any better, but I just want to be careful.
