dash and ash are identical.

Yep - it's an ACL issue. Since you (cobbch) are not the owner
(Administrators), and your group membership (root, Administrators, Users,
SophosUser) does not include the group owner (SYSTEM), and since the mode does
not grant any permissions to others, dash's use of stat() thinks you have no
rights. But in reality, the ACLs state that anyone in group users (which
includes you) has additional rights beyond what stat() can see, and hence
euidaccess() (which bash uses) gives the correct answer.
I've reported this upstream. Meanwhile, I guess that means its time for me to
respin a dash package. Thanks for the report.
