But being sans-automation, your UUIDs or BLKIDs aren't fit for

for boot materials, this is the case.

I'm fine with manually editing fstab, in which I use labels instead of uuid ...
$ grep x7 /etc/fstab
LABEL=x7b / ext4 defaults,noatime 1 1
LABEL=x7bboot /boot ext4 defaults,noatime 1 2
manually changing /boot/grub2/install.sh and if needed, /boot/grub/device.map,
and then using chroot or systemd-nspawn to update the grub2 boot loader,
either from another install on the same system or from a live iso.

I've done it enough times, it's pretty easy to remember the steps needed, or
debug and fix if I've missed one.
