This gives more permissions to services (e.g. network access to services which require this) when they are started as an automatic service jail. The sshd patch is important for the sshd-related functionality as described in the man-page in the service jails part. The location of the added env vars is supposed to allow overriding them in rc.conf, and to hard-disable the use of svcj for some parts where it doesn't make sense or will not work. Only a subset of all of the services are fully tested (I'm running this since more than a year with various services started as service jails). The untested parts should be most of the time ok, in some edge-cases more permissions are needed inside the service jail. Differential Revision: https://reviews.freebsd.org/D40371
