# Upgrade from etch to lenny

make apt sane:

        echo 'APT::Install-Recommends 0;' > /etc/apt/apt.conf.d/local-recommends


add volatile to sources list and upgrade (at least the archive keyring)

	grep volatile /etc/apt/sources.list || cat >> /etc/apt/sources.list << EOF
	deb     http://volatile.debian.net/debian-volatile etch/volatile  main

turn off samhain

	/etc/init.d/samhain stop


maybe turn off exim

	/etc/init.d/exim4 stop
	mv /etc/rc2.d/S20exim4 /etc/rc2.d/K20exim4 # so it stays down


install deborphan, clean up

	apt-get install deborphan dialog

purge removed packages

	echo "really purge these [y/N]?"; read ans; [ "$ans" = "y" ] && dpkg --purge `dpkg --get-selections | awk '$2!="install" {print $1}'`


remove cruft and prepare sources.list update

	rm -f /etc/apt/sources.liste
	mkdir -p /etc/apt/sources.list.d


change sources list entries to lenny:

	mirror=`cat /etc/apt/sources.list | awk '/debian/ {print $2; exit}'`
	echo "Mirror is $mirror"; echo "Fix stuff if this seems wrong"; echo "XXXXXXXXXXXXXXXXXXXXXXX"
	echo "## VERIFY THE MIRROR IS CORRECT ##"; read


write new sources.list.d/ entries:

	(! [ -e /etc/apt/sources.list ] || mv /etc/apt/sources.list /etc/apt/sources.list-oldetch) &&
	cd /etc/apt/sources.list.d &&
	cat > backports.org.list << EOF &&

update apt list

	apt-get update


upgrade

	apt-get install locales-all


rest follows

	apt-get dist-upgrade


reject changes to /etc/pam.d/sudo (puppet will install a new file later anyway)

merge changes into /etc/munin/plugin-conf.d/munin-node (change new and accept (A)):

	sed -i -e 's/adm$/adm, maillog/' /etc/munin/plugin-conf.d/munin-node.dpkg-new

 * keep local (i.e. reject (N)):
  * all changes relating to exim  (in /etc/exim4 and in logrotate)
  * /etc/ldap/ldap.conf
  * /etc/nagios/nrpe.cfg
  * /etc/samhain/samhainrc
  * /etc/munin/munin-node.conf
 * merge: /etc/logrotate.d/apache2
 * take new: /etc/apache2/apache2.conf
 * maybe take new: /etc/apache2/ports.conf
 * change ServerTokens from "Full" to "ProductOnly" in /etc/apache2/conf.d/security


update nagios on samosa  (add host to lenny hostgroup)

maybe install [[puppet|puppet-setup]]

check for obsolete packages

	/usr/lib/nagios/plugins/dsa-check-packages

clean up old libs

	orphaner
	orphaner -n
	orphaner -a
	orphaner -a -n


purge removed packages

	dpkg --get-selections | awk '$2!="install" {print $1}'
	echo "really purge these [y/N]?"; read ans; [ "$ans" = "y" ] && dpkg --purge `dpkg --get-selections | awk '$2!="install" {print $1}'`

possibly reboot

re-enable exim

	mv /etc/rc2.d/K20exim4 /etc/rc2.d/S20exim4
	env -i /etc/init.d/exim4 start
