Yes -- I have NetworkManager on this system (Debian
testing) and the scripts in /etc/network/*.d get run
at the right times.  So it doesn't really make sense
to have to start up a process as part of my session
just to listen for D-Bus signals and run the scripts,
when the system-level scripts are already getting run.
I have mostly short-lived processes, not big things
that stay running all the time.  Except Evolution, but
I'm looking for something to replace that.  I like the
"I Want Sandy" approach of having a virtual assistant
address that you copy on the mail you send out saying
that you're going to do something, or the mail you
send out telling someone else to do something, and
then getting reminders.
