>Description:
I tried some of these filesystem flags, on a test directory and found out that unsetting the sappend flag doesn't work. I got the following:
#chflags nosappnd test/
#chflags: test/: Operation not permitted

ls -lo says there's the flag on the dir, as i set it

>How-To-Repeat:
#chflags sappnd test/
then try to unset with nosappnd
>Fix:
I think it checks that if any changes can be made to the directory, but of course it's in append only mode so no changes can be made.
