Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
u6rd is a user-space 6rd (RFC 5569) implementation, which uses
tun(4) and the raw socket interface.
It runs on the 6rd border router of a 6rd site that is isolated from
the native IPv6 Internet. In other words, it does not provide the
functionality of 6rd "relay" routers.
