In current Fedora CoreOS we have 128 bit inodes for /boot, and this appears to be the default of `mkfs.ext4` for our chosen size of /boot:

[root@cosa-devsh ~]# truncate -s 384M /var/tmp/disk.img
[root@cosa-devsh ~]# mkfs.ext4 /var/tmp/disk.img

Ah but with a 512M disk I do get 256 bit inodes, I bet that's the difference.

Or, maybe it's an Anaconda thing to override it? 

Anyways...for now I may just get the PR merged to update FCOS's /boot.
