Added updated script and notice re: outdated instructions

I used a modified archbootstrap script which can be found at http://forzza.systs.org/openvz-misc/
|}
=== bootstrapping Archlinux ===
Syntax:
{{Note|Please use mirrors! A full list of Archlinux mirrors: http://wiki.archlinux.org/index.php/Mirror}}
=== enter the Build with chroot ===
All the commands below are executed from the root shell. I this howto "chroot" is used to enter as NEWROOT, a BUILD-VE must not be created!
CT0_# chroot /vz/template/$DIST/$VERSION/$ARCH/
==== setting DNS server ====
For the chroot BUILD we also need to specify a DNS for it:
BUILD_# mv /etc/resolv.conf.pacorig /etc/resolv.conf
==== update and install packages ====
Update (sync) pacman cache and update installed packages
BUILD_# pacman -S openssh quota-tools iproute
==== fix /etc/mtab ====
Add symlink /proc/mount /etc/mtab
BUILD_# ln -s /proc/mounts /etc/mtab
==== fix /etc/inittab ====
Remove getty lines from inittab:
BUILD_# sed -i -e '/getty/d' /etc/inittab
==== create device nodes ====
Create device nodes at /dev, like console, full, null, zero, urandom, ptmx and fifo of initctl
BUILD_# mknod -m 666 /dev/zero c 1 5
==== sysinit script modification ====
Remove deleting of /etc/mtab in /etc/rc.sysinit and add mounting of /dev/pts
[...]
==== modify the main configuration file ====
BUILD_# nano /etc/rc.conf
DAEMONS=(syslog-ng network netfs crond ssh)
==== enable ssh connections ====
{{Note|All connection are disabled to VE, see /etc/hosts.deny, only affected server built-in with libwrap}}
BUILD_# echo "ssh: ALL : ALLOW" >> /etc/hosts.allow
==== lock (disable) the root account ====
BUILD_# passwd -l root
==== exit the chroot to CT0 ====
BUILD_# exit
=== build a exclude list ===
Shrink the OS-Template, so not all files needed in a VE - OS - TEMPLATE
CT0_# find ./root/.bash_history >> ../exclude.list-$ARCH
=== create OS template ===
CT0_# tar --numeric-owner -X ../exclude.list-$ARCH -czf /vz/template/cache/arch-0.8-$ARCH-minimal.tar.gz ./
=== use the OS template ===
CT0_# vzctl create <VEID> --ostemplate arch-0.8-$ARCH-minimal ...
=== update the OS template ===
To update a template is really easy, enter the build with chroot, performing upgrade task
Update the exclude list, and pack upgraded OS - Template
