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
