# FIXME: libseccomp (as of 2.6.0) doesn't know the open_tree_attr() system call
# yet which we need. Thus, applying any system call filter would block this
# system call unconditionally, which is not desirable. This should be added
# back once libseccomp is updated. See
# https://github.com/seccomp/libseccomp/issues/465
