Reserving 26 for a new s390 bot in a follow up CL to avoid yet another master
restart.

[Sergiy Byelozyorov, 2016/04/05 15:04:09]

Not sure I understand. Are we going to decommission slave26-c3? what is s390?
How would it save us master restart?

[Michael Achenbach, 2016/04/05 17:32:51]

s390 is an architecture and v8 is going to port it. For that I'll add a builder
on the waterfall client.v8.ports in a different CL. I'll save restarting
client.v8 another time if I don't switch the slave in that follow up CL
(restarting client.v8 is annoying as many devs rely on it and it's slow on
startup).
