The previous approach to installation is: try this easy one first, and
if it fails, try the hard one.
This commit streamlines the installation experience by minimizing
references to such procedures.
This commit also removes verbose comments from Root on ZFS installation
guides.
As the upstream has fixed glibc, its section is also removed.

because they weren't.
I made one small textual change when cleaning this up.
