RE: [K12OSN] OT: Apple Imac lab


Stick to your guns on the OO.o for the Macs, as I think that’s the big
slippery slope.  

You volunteer your time adminning the Linux boxes.  Adding this lab of Mac's
will add a significant amount of work to you.  What I don't understand is
why you agreed to take on that extra work.  

If I were you, I would drop a few "this is a LOT of work I am not sure I can
do on a volunteer basis... We may need to look at a support contract for all
these Macs..."  If you have a few quotes from Mac shops about supporting
that lab with comparable uptime to the LTSP system (is that 99.999 or
99.9999 uptime...), I think you will find a lot more traction for your side
of things.  Just make sure to spec the quotes correctly so that they have to
interface seamlessly with the existing servers, have the ability to netboot
as LTSP/Win workstation, and whatever else you can think of.  I strongly
suspect such a contract will cost many times more than the lab itself.
