Hi Saul,

I had a bit of a discussion with bluelightning and peteru in #oe. We came to 
the conclusion that having ssh connections still up after service stop is 
considered to be the correct behaviour.

On the other hand, not closing ssh connections on shutdown is generally 
considered a bug by distros, although it is considered a minor one. This 
generally requires connections being killed before network is brought down, 
which might be complicated with sysvinit. These are the links from other 
distros:

https://bugs.gentoo.org/show_bug.cgi?id=259183
https://bugs.archlinux.org/task/31250

Long story short: it would be nice to gracefully close ssh connections on 
shutdown before terminating network connections, but it's a minor issue, and 
probably not worth the effort of fixing.

Bests,
Diego
