This is interesting.  Is it possible for me to join this bi-weekly call?
If so, can you send me info on how to join?

I'm extremely interested in this.  I was planning on creating some boot time instrumentation
and a boot time test, this summer (before LPC in September).  I would be
thrilled to talk to other developers about this (either by e-mail, in your bi-weekly
call, or at Plumbers) before I get too far into it.

If others are working on measuring, testing,  or reducing boot time, please
consider joining the "Embedded and IOT" micro-conference at Plumbers in September.

One of the chief topics of that micro-conference will be boot time.  Please contact me
and I can let you know instructions for submitting a topic proposal for the event.
(Or just submit something at: https://lpc.events/event/18/abstracts/)
The instrumentation and testing of boot time would be a great topic for the
micro-conference!!
