Subject: Please muscle memory when dhclient $if is run and request a new lease.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=bc837866265349424953a2f715f5a8b8b5231b72;p=openbsd

Please muscle memory when dhclient $if is run and request a new lease.
An upcoming diff for dhclient(8) will make it exit when it discovers
an autoconf flag at startup.
"Quite a pleasing diff." deraadt@
