Prerequisites:

	squashfs support in your host kernel
	  (http://squashfs.sourceforge.net)
	enough free space to install a chroot crux and build iso packages
	pkgutils installed on the host, if not crux


Process:

# download the current iso (or 2.3 if you want to do lots of updates)
# and mount it via loopback

 wget crux-2.3-latest.iso
 mount -o loop crux-2.3-latest.iso /mnt/loop

# create an empty crux chroot and package database

 mkdir -p /opt/crux-chroot/var/lib/pkg
 touch /opt/crux-chroot/var/lib/pkg/db

# install the packages from the iso into the chroot

 for i in /mnt/loop/crux/{core,opt,xorg}/*.pkg.tar.gz; do pkgadd -r /opt/crux-chroot $i; done

# prepare the chroot (mount up /dev, /proc, copy kernel sources, etc.)

 mount -t proc proc /opt/crux-chroot/proc
 mount -o bind /dev /opt/crux-chroot/dev
 cp -L /etc/resolv.conf /opt/crux-chroot/etc/
 cp -r /mnt/loop/crux/kernel/* /opt/crux-chroot/usr/src/

# checkout your new_iso, core, opt, and xorg git WCs
# (I just copy them from my user's local WC)

 git clone git+ssh://crux/home/crux/scm/system/iso.git
 (cd iso; git branch new_iso origin/new_iso; git checkout new_iso)
 git clone git+ssh://crux/home/crux/scm/ports/core.git
 (cd core; git branch 2.3 origin/2.3; git checkout 2.3)
 # repeat for opt, xorg
 cp -a iso /opt/crux-chroot/usr/src/
 cp -a core opt xorg /opt/crux-chroot/usr/src/iso/ports/

# chroot

 chroot /opt/crux-chroot /bin/bash
 export PS1="(chroot) $PS1"

# update the chrooted system
# (may be necessary to get some ports to build for the iso but may be
#  skippable.)

 mv /etc/ports/contrib.rsync{.inactive,}
 ports -u
 prt-get sysup

# install squashfs-tools (iso squashfs) and elinks (handbook/release notes)
# (do the elinks part from your host system instead of the chroot
#  if you prefer.)

 cd /usr/ports/contrib/squashfs-tools
 pkgmk -d -i
 cd /usr/ports/opt/elinks
 pkgmk -d -i

# download the handbook and release notes

 cd /usr/src/iso/doc/handbook
 ./get_wiki_handbook
 ./get_wiki_release_notes
 cd ../..

# bootstrap the iso

 make bootstrap

# build it

 make iso

-------------------

Preparing a netinst mirror: (after building the iso)

 cd ports
 ./checkdups # remove duplicates
 ./gen-mirror <distdir>

Upload <distdir> to your mirror location.
