Description
The ACL generated for mode 0077 looks like this:
owner@:rwx-----------:------:deny
owner@:------aARWcCos:------:allow
group@:rwxp--a-R-c--s:------:allow
everyone@:rwxp--a-R-c--s:------:allow
It should look like this instead (note the "append" permission in the first entry):
owner@:rwxp----------:------:deny
owner@:------aARWcCos:------:allow
group@:rwxp--a-R-c--s:------:allow
everyone@:rwxp--a-R-c--s:------:allow
Suggested patch looks like this:
