 I also ran into problems with ktruss recently, on NetBSD 5.0.1/i386.
 For example, an open() system call which ktrace + kdump reported like
 this:
 
  15159      1 testprog CALL  open(0xbb80208c,0,0xbfbfe7e8)
  15159      1 testprog NAMI  "/dev/rwd0a"
  15159      1 testprog RET   open 3
 
 ktruss reported like this:
 
  11230      1 testprog open("/etc/malloc.conf", 0, 0xbfbfe7e8) = 3
 
 Note how the argument "/dev/rwd0a" has turned into "/etc/malloc.conf".
