Per the email thread, it seems that FreeBSD's FUSE is sending extra truncate events, even for files opened read-only. Since this also happens on the example FUSE file-system, I don't think there's anything tup can do to prevent it (unless there is some hidden option I don't know about?) Eg:

t1$ ./fusexmp -f -d tmp
t2$ cd tmp/home/marf
t2$ cat ok.c

Even though we are opening the file read-only with cat, FUSE calls truncate() on it, which modifies its mtime. As far as tup knows, it's writing to the file. We'll need to figure out why FUSE is doing this.
