Fortunately, even in the Linux case, it doesn't seem to mess up quotas.
The argument to [f]truncate is meant to be a size_t not a ssize_t, so
probably this is a signed/unsigned bug. The man page says that it should
truncate a file to at most the specified size, so the correct behaviour
should be
truncate("x", -1)
kernel: current size 0 < new size 2^32 - 1
kernel: return success with no action

(NB: StarOS 4.1.1 in the above list is basically SunOS 4.1.1 for one type of
sun4x [the Star 910/VP])
