-In article <12684 at mimsy.UUCP> I wrote that the sequence
-> open
-> write (moves seek pointer)
-> ftruncate
-> write
->will create holes, since the second `write' is not at the beginning
In article <26556 at oliveb.olivetti.com> jerry at olivey.olivetti.com
(Jerry Aguirre) notes:
-What is interesting is that even if the open file has been placed in
-FAPPEND mode there will still be holes. I view this as a bug.
Fixed in 4.3BSD-tahoe (if not earlier).
