<para>The &man.burncd.8; utility now allows commands (such as

<para>The <literal>create</literal> command of the &man.gpt.8;

<para>The &man.newfs.8; utility now supports a <option>-n</option>
|

flag to suppress the creation of a <filename>.snap</filename>

directory on new file systems. This feature is intended for use
|
|
on memory or vnode file systems that will not require snapshot
|
|
support. &merged;</para>
|
|
|
|
<para>The &man.ifconfig.8; utility has been restructured. It is
|
|
now more modular and flexible with respect to supporting
|
|
interface-specific functionality. The 802.11 support has been
|
|
updated to support recent changes to the 802.11 subsystem and
|
|
drivers.</para>
|

<para>Support for abbreviated forms of a number of &man.ipfw.8;

temporary backward compatibility for the old names.</para>

<para>The &man.ppp.8; program now implements an

<option>echo</option> parameter, which allows LCP ECHOs to be
|
|
enabled independently of LQR reports. Older versions of

&man.ppp.8; would revert to LCP ECHO mode on negotiation

|
socket (<filename>/var/run/logpriv</filename> by default),

with <literal>0600</literal> permissions to be used
|
|
by privileged programs. This prevents privileged

<para>The &man.tcpdrop.8; command, which closes a selected TCP

<para>&man.whois.1; now supports

<para>To use different &man.rc.conf.5; knobs with different
