# 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"
* say no to other other questions.

commands:

	sed -i "s#wheezy#jessie#g" /etc/apt/sources.list.d/debian.list /etc/apt/sources.list.d/security.list &&
	dpkg --clear-avail &&
	if [ -e /etc/apt/sources.list.d/buildd.debian.org.list ]; then
		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 -f /var/state/samhain/samhain_file /var/lib/samhain/samhain_file &&
	samhain --foreground -t init -p none -s none -l none -m none &&
	(puppet agent -t || true) &&
	apt-get dist-upgrade &&
	apt-get --purge autoremove &&
	while [ "$(deborphan -n | wc -l)" -gt 0 ] ; do apt-get purge $(deborphan -n); done &&
	dpkg --clear-avail &&
	apt-get clean


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:

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

re-init samhain

	(puppet agent -t || true) &&
	(puppet agent -t || true) &&
	samhain --foreground -t init -p none -s none -l none -m none

Add the new ed25519 ssh host key:
	run
	  echo; echo "cat << EOF | ldapmodify -ZZ -x -D uid="\$USER",ou=users,dc=debian,dc=org -W -h db.debian.org"; echo "dn: host=`hostname`,ou=hosts,dc=debian,dc=org"; echo "changetype: modify"; echo "add: sshRSAHostKey"; echo "sshRSAHostKey: `cat /etc/ssh/ssh_host_ed25519_key.pub `"; echo; echo "EOF"; echo
	and paste it on draghi.
	
update dsa-nagios.git (add host to jessie hostgroup)

reboot.
