problems
--------
- dsa-check-packages points to /bin/true on hosts running in the future

todo for upgrades
-----------------
test jenkins-test-vm upgrade before doing jenkins
	-> cucumber problems reported by fil
resolve issues on pb2+6+12+16:
	no amd64 kernel for i386? manually done, needs to go into update_jdn
	compare sshd_config from stretch with the one we're using (from jessie)
wait with upgrading armhf nodes until next week as vagrant has no time until then


to be done once all hosts run stretch: squid
--------------------------------------------
It seems the squid configuration moved from /etc/squid3 to /etc/squid.  postinst
script takes care of moving the files, but we should eventually:
1) move them in our git repo too
2) delete /etc/squid3 from the hosts
3) install squid instead of squid3 in update_jdn (once all hosts are upgraded) - that's going to mark the package as manually installed
4) apt purge squid3

to be done once all hosts run stretch: sshd_config
--------------------------------------------------
/etc/ssh/sshd_config - the currently running one is the one from jessie, we should update_jdn to the one from stretch


done for upgrades
-----------------
upgrade of all i386 nodes
upgrade of jenkins-test-vm in progress
