Testing d-i built against testing udebs again, I can replicate this issue now. I suppose this might be some component getting bigger over time, and pushing the limit somehow. And the various builds I tried back in January might have been tiptoeing around that limit… Looking at `free` with this netboot-gtk mini.iso build, inside kvm, with 1G RAM, `used` is ~100M, `free` is 500+ M, and yet, cryptsetup gets OOMK'd. Is cryptsetup being stupid and miscomputing RAM requirements for that setup? (ISTR LUKS2 means heavier computation, tweaked depending on hardware, but I haven't followed that closely.) The memory pressure at this particular point of the installation process seems quite low, so crashing with free at 50% feels very wrong to me… Cheers, -- Cyril Brulebois (k...@debian.org) <https://debamax.com/> D-I release manager -- Release team member -- Freelance Consultant
