Neat. I wish OpenSSH better support this use case. The instruction involve multiple moving parts on top of OpenSSH (s6-ipcserver, socat or custom scripts) and a number of extra options for the client. That probably adds overhead. It would probably be easier and more efficient if OpenSSH would directly support Unix sockets.
That sounds a bit contradictory but there’s an important details. Part of the accusation seems to be about picking winners, ie giving subsidies to specific companies rather than the sector as a whole.
If that’s true then a tweak to subsidies might technically solve the issue without changing the EU-China competition balance.
IMHO the EU should focus on carbon border tax, and on doing it quickly and efficiently. The idea is taxing import from countries that don’t tax pollution, or at least less than the EU does, to make competing companies subject to similar emissions tax/regulation.
