Last time I looked, the exit value from ftp(1) was 0 in circumstances
like these. This meant that bsd.pkg.mk and the infrastructure has to
check for correct reception of the whole distfile, not ftp(1).
You can set FAILOVER_FETCH in mk.conf or in the environment or on the
command line, and the checksum on the distfiles will be used to ensure
that the correct distfile has been fetched.
This was added in September 1998, and is used by the bulk build mechanism
to get the correct distfile downloaded.
