This might be a easy upgrade but it&#8217;s a significant mile stone.<\/p>\n<ul>\n<li>80386 processors are not supported anymore.<\/li>\n<li>A new sysctl called <i>security.jail.enforce_statfs<\/i> that controls what mounts are visible in a jail, I recommend setting this to 1 if you are using <a href=\"http:\/\/www.devco.net\/archives\/2005\/11\/01\/sharing_directories_between_jails_using_nullfs.php\">nullfs to share directories<\/a> that way jail users can see for themselves that certain directories are mounted read only for example.<\/li>\n<li>The IPDIVERT kernel option now causes a module to be built that is loadable at run time!  Also libalias now supports being built as a kernel module.<\/li>\n<li>ipfw have a option to only match packets for a given jailid, this is now support with mpsafenet=1<\/li>\n<li>ipfw can now tag <a href=\"http:\/\/www.freebsd.org\/cgi\/man.cgi?query=altq&#038;sektion=4&#038;manpath=FreeBSD+6.0-RELEASE\">altq<\/a> packets<\/li>\n<li><a href=\"http:\/\/www.freebsd.org\/cgi\/man.cgi?query=bsdiff&#038;sektion=1&#038;manpath=FreeBSD+6.0-RELEASE\">bsdiff(1)<\/a> and <a href=\"http:\/\/www.freebsd.org\/cgi\/man.cgi?query=bspatch&#038;sektion=1&#038;manpath=FreeBSD+6.0-RELEASE\">bsdpatch(1)<\/a> has been added for binary diffs and patching<\/li>\n<li>libarchive and therefore bsd tar now supports ISO files and ZIP files, try <i>tar -tvzf blah.zip<\/i> and <i>tar -tvf blah.iso<\/i> to see this in action, fantastic!<\/li>\n<li>Two utilities &#8211; <a href=\"http:\/\/www.freebsd.org\/cgi\/man.cgi?query=pgrep&#038;sektion=1&#038;manpath=FreeBSD+6.0-RELEASE\">pgrep(1)<\/a> and <a href=\"http:\/\/www.freebsd.org\/cgi\/man.cgi?query=pkill&#038;sektion=1&#038;manpath=FreeBSD+6.0-RELEASE\">pkill(1)<\/a> has some new options, these utilities makes it easy to find and kill processes by name<\/li>\n<li>The fantastic <a href=\"http:\/\/www.freebsd.org\/cgi\/man.cgi?query=portsnap&#038;sektion=8&#038;manpath=FreeBSD+6.0-RELEASE\">portsnap(8)<\/a> utility is now installed by default.  This replaces the old cvsup method of keeping your ports tree in sync and is well worth investigating.
