LXC VMs become unbootable when upgraded to jessie.
The upgrade migrates systems automatically to systemd, after which the
VMs won't be able to boot.
The simplest workaround currently is to upgrade and then, before
rebooting, to switch back to sysv.
That sounds like something we should be fixing, rather than documenting.
OMMV, but I'm not particularly keen on the release notes explicitly
suggesting that people go out of their way not to run the default init
system (quite aside from the fact that we don't currently know whether
upgrades will actually change the init system at all for most users).
