commit 66705948c0639a7061a0d0753266da7685badfec
Author: djm at openbsd.org <djm at openbsd.org>

    upstream commit
    
    Mark the sshd_config UsePrivilegeSeparation option as
    deprecated, effectively making privsep mandatory in sandboxing mode. ok
    markus@ deraadt@
    
    (note: this doesn't remove the !privsep code paths, though that will
    happen eventually).
