The existing default_context_t (no 's') type seems reasonable for the
contexts directory and users subdirectory.  Note however that this will
likely require new allow rules in the policy, as some domains may have
previously had read access to the files under etc_t and will now need
read permission to default_context_t.

/etc/selinux/config should have a different type.  We could define a
type for the /etc/selinux directory and simply use that type for the
config file as well to ease maintenance.  That would also make sense
from a control perspective - you are unlikely to be allowed to modify
the /etc/selinux directory (e.g. add new policies under it) unless you
can also modify /etc/selinux/config to set the type.  No other files
under /etc/selinux would normally have that type, as everything else is
a subdirectory and has a separate type assigned.
