I note that core 169 testing, on x86_64, no longer has an initramfs file in /boot, yet boots and runs quite readily. Although I rarely use Ubuntu, I understand that it dropped need for initramfs some time ago.
OTOH, the lack of uboot in upgraded armv6l and aarch64 prevents those from rebooting. Is this a repeat of the issues with core 167, where there was insufficient space to collate initramfs ?
Could the release announcement briefly point out whether initramfs is/is-no-longer required.
