I think it's because we are very afraid of telling people what to do.  I
think if we had to start all over again, I would vote for exactly two ways
to install in an LPAR:

1.  Boot (load) from removable media or FTP server and install from the
same source (needs that new device driver!!).  The DVD is in the HMC drive
or loaded on my laptop with an FTP server :-).

2.  Boot from SCSI and install from the boot device (needs 'install from
directory'!!).   That could be physical DVD:or contents copied to a SAN
disk.

This avoids what I like to call the"Installation Two-Step."   No need to
try to loop out-of-band back to the media.
