Hi Mike, I mean more at the linking process, as ld's memory usage gets so high. I can't help but think that if it wasn't linking say amdgpu, ld would use a lot less memory. Though, I'm not sure one can drop parts being linked without recompiling? It'd be nice to have a 512MB server comfortable booting without swap, in a heavy multi-tenant usecase. -Henrich
