# Upgrade from squeeze to wheezy

Make sure to coordinate with whoever uses the host, be it the buildd
operator, the QA team, the ftp team or just announce it if it's a
general developer box.

on buildds:

	cd ~buildd
	sudo su - buildd
	touch NO-DAEMON-PLEASE EXIT-DAEMON-PLEASE && exit

	now wait for the buildd to quit

upgrade stuff:

* answer question to libc6 "Restart services automaticaly" with "yes"
* answer "Yes" to changes of /etc/default/rcS, [BR#694928](http://bugs.debian.org/694928)
* and change "FSCKFIX=yes" afterwards, at least on hardware without remote access (like arm*)
* say no to other other questions.

commands:

	sed -i "s#squeeze#wheezy#g" /etc/apt/sources.list.d/debian.list /etc/apt/sources.list.d/security.list &&
	dpkg --clear-avail &&
	rm -f /etc/apt/preferences.d/dsa-bacula-client &&
	if [ -e /etc/apt/sources.list.d/buildd.debian.org.list ]; then
		rm -f /etc/apt/preferences.d/buildd &&
		sed -i "s#squeeze#wheezy#g" /etc/apt/sources.list.d/buildd.debian.org.list
	fi &&
	apt-get update &&
	apt-get install dpkg apt samhain &&
	service samhain stop &&
	apt-get dist-upgrade &&
	rm /var/state/samhain/samhain_file &&
	samhain --foreground -t init -p none -s none -l none -m none &&
	(puppet agent -t || true) &&
	apt-get dist-upgrade &&
	c_rehash /etc/ssl/debian/certs &&
	c_rehash /etc/exim4/ssl &&
	apt-get --purge autoremove &&
	while [ "$(deborphan -n | wc -l)" -gt 0 ] ; do apt-get purge $(deborphan -n); done &&
	apt-get purge liblzma2 lzma &&
	dpkg --clear-avail &&
	apt-get clean


if /etc/apache2/apache2.conf was not changed, remove the include for httpd.conf.

purge removed packages

	dpkg --get-selections | awk '$2=="deinstall" {print $1}' &&
	echo "really purge these [y/N]?" && read ans && [ "$ans" = "y" ] && dpkg --purge `dpkg --get-selections | awk '$2=="deinstall" {print $1}'` &&
	echo "These are not at install:" && dpkg --get-selections | awk '$2!="install" {print $1}'

more clean ups:

	apt-get purge arrayprobe
	/usr/lib/nagios/plugins/dsa-check-packages | tr -d ,
	apt-get --purge autoremove

maybe
	apt-get install firmware-linux

update dsa-nagios.git (add host to wheezy hostgroup)

reboot

verify ipv6 routing still works.

re-init samhain

	samhain --foreground -t update -p none -s none -l none -m none
