mkfs's arguments are
mkfs [options] [-t type] [fs-options] device [size]
So it seems our MKFS_OPTS are really supposed to be fs-options, rather
than options to mkfs itself.
Why didn't we notice? It's quite a trap -- mkfs.ext2 has a "-t"
option, so when we're calling
$ mkfs -i 4096 ... -t ext4 ...
We actually just fall-back to the default from the mkfs wrapper which
is mkfs.ext2 which works! But when you make that, say, xfs, we're not
calling the right wrapper at all.
Also update documentation

speedup section explains the user how to sppedup image build by using
tmpfs. The correct user guide to have this section, is the user guide
about image building rather than the installation user guide.

End user docs would benefit from a section about the byte-to-inode
ratio, and why it's set the way it is. This update explains why
and how to manipulate the ratio depending on the intended use.

Our docs are very developer focused. Lets create a separate user guide
to help new users get started.
