Is it still necessary to have the images directory in the same
directory as
the iso for HD installs now,
Yes.
or has this been fixed so that the iso alone is
all that is needed?
It won't be fixed.
If the images directory is still required, does this apply to nfs,
http or
any other kinds of install??
It applies to any kind of ISO install. For non-ISO installs, there are
some implicit assumptions made about the location of an install.img
relative to the location of the tree, but these are all tweakable with
the repo= and stage2= parameters.
