Following discussions that happened on Monday, I limited the number of
Berlin workers emulating aarch64 builds by half (see
abfb17bfec0ba41399fb60e91aa0e98087fab469 on maintenance).

I also raised the number of Cuirass remote workers by machines to four
(see a5df328e5c833ca2d28105280484626bf4c1adb1 on maintenance).

Thanks to Ricardo support I was able to setup a Wireguard tunnel between
berlin and the overdrive1. It seems to work pretty well and
https://ci.guix.gnu.org/workers shows that it is building some packages.

I plan to connect the remaining overdrive machines, 2 at Tobias and 1 at
Andreas places. If this model of connecting build nodes through VPN
works sustainably, connecting more ARM workstations hosted at individual
could be a way to proceed.

WDYT?

Thanks,

Mathieu
