Yes.  This is a Linux kernel driver limitation, so we can't work
around it.  Xastir has code in it to drop to regular user privileges
when it doesn't need the SUID root privileges though, so you're
_relatively_ safe doing this:


    su
    chmod 4755 /usr/local/bin/xastir


We make no guarantees that it's safe to do the above, but to my
knowledge nobody's been hacked into via Xastir so far to gain root.
