9d13084c41 Add squashfs output image format
The squashfs format brings a couple of advantages over the other
formats. Image is often an order of magnitude smaller and it can
be used natively, either as an initrd, either with loop mount.

5e2330d89c Put MKFS_OPTS after filesystem type
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

24d1527111 Move speedup section to image building guide
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.

5e9c451d5f Document byte-to-inode ratio
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.
