I've been using "Diskless install using PXE from the LiveCD" (https://wiki.gentoo.org/wiki/Installation_alternatives#Diskless_install_using_PXE_from_the_LiveCD) to boot the minimal installation CD via PXE with great success for quite a while, but the recent versions of the CD (anything created in 2025) don't seem to work. The boot process gets stuck in various steps depending on which hardware the machine has, such as initializing the disk interface or the network interface. The problem is reproducible in QEMU and VirtualBox, as well as physical machines, even though booting straight from the .ISO file works fine in all cases. It does work fine with 20240714 build, so something must have changed between then and now.
