For reasons that totally made sense at the time, my Linux server has a 250 megabyte /boot volume. This is now uncomfortably small (InitRDs are stupid big now) and I want to switch to just / without a separate /boot.
The current / is ext4 and an LVM volume. The OS is Ubuntu Server 16.04. Can I simply update /etc/fstab, comment out the line for /boot, move that partition's contents into the corresponding /boot directory on the / partition, then update grub and profit? I don't really understand LVM and use it only because the Ubuntu installer did a good job of selling its future-proof capabilities.
If I can't do this easily, eh, it's getting about time to buy a bigger disk for that computer anyway and that'll give me an excuse to redo it less wrong.
