I'm confused. base.aa, etc, are a tar file, so I don't
entirely understand how this would be different? The
current installer does the equivalent of
cat base.* | tar -xf -
I can see one advantage and one disadvantage of installing
a specification file (which references other files) instead:
Plus: The specification file can re-use the existing
files on CD, so you don't have, e.g., one copy of /bin/sh
on the live CD and another buried in base.tgz. This
could save space.
That is exactly what I was referring to above. And AFAIK DragonflyBSD
does it in a similar way. They simply copy the live CD onto the HDD.
Minus: Installing a specification file this way would
be slower because you then have to read a lot of small
files off of CD.
True, but couldn't we optimize the ISO layout so it will be a near
sequential read of the CD? This should be done for every live CD
anyway to avoid excessive seeks during boot up.
