cd /usr/ports/net/cvsup-without-gui/ && make install clean && rehash && cvsup -g -L2 /usr/share/examples/cvsup/ports-supfile -h cvsup.planetmirror.com

X -configure

distfiles.yourdomain.net and add it as a
MASTER_SITE_OVERRIDE=http://distfiles.yourdomain.net/${DIST_SUBDIR}                                             in /etc/make.conf
The documentroot is pointing to /usr/ports/distfiles and if I need
to get somethign which needs to be installed everywhere I fetch it
there once and then do the fetching on all the other machines.                                                  
pkg_add -r <package>

pkg_tree                                                                                                        
In /usr/ports, make fetch

install /usr/ports/linux_base-debian
edit /etc/rc.conf to have linux_enable="YES"
or sudo kldload linux
chroot /compat/linux /bin/bash

install portupgrade
portinstall -vpP

16:27 <@Chaos> and then cp /usr/share/examples/etc/make.conf /etc
16:27 <@Chaos> edit that and uncomment the stufff about SUP
16:27 <@Chaos> if you installed /usr/src cd /usr/src && make update

16:40 <@Chaos> it'll do /usr/src then /usr/ports
16:40 <@Chaos> once thats done
16:40 <@Chaos> do a make buildworld
16:41 <@Chaos> and while thats building create /sys/i386/conf/<hostname> from
               GENERIC and change / add / remove stuff to match your HW
16:41 <@Chaos> then do a  cd /usr/src && make buildkernel KERNCONF=<hostname>

17:05 < ^Sarge^> make buildworld && make buildkernel && mergemaster && init 1
17:06 < ^Sarge^> or you could just cheat n do make world && mergemaster && make kernel && init 6
