A different point of view
.
I would like to propose that Klaus K view this survey from a different point of view.
Rather than assume we all need a DVD-size Knoppix, and ask 'Who needs a CD-version of Knoppix ?',
let's ask 'Who needs CD-size Knoppix? and, Who needs a DVD-size Knoppix?
I suggest everyone needs a CD-size Knoppix, almost no-one needs a DVD-size Knoppix, and
almost everyone would like some elements of the DVD-size Knoppix in addition to that
which the CD-size Knoppix provides.
Knoppix has a built-in procedure for combining individual isos which works elegantly so long
as there is no overlapping use of the same final memory locations. This built-in capability
is often used to provide additional material on CeBIT products.
It is conceivable, to me at least, that Knoppix might alternatively be provided by issuance always
of at least a CD-size Knoppix iso, and as time permits of the provider, additional isos which
add additional capabilities in packages each of 4 Gb or less. Said capabilities of the
CD-size iso and the totality of these additional isos amounting in the aggregate to that of
a former DVD-size Knoppix.
Knoppix currently may combine up to eight isos, two should suffice in principle to allow for
both a CD-size iso and a DVD-size adapter iso . But, it might be wiser to use more isos, each with
some some different but additive specialization. And I expect it might be possible to so apportion
the aggregate additional capabilities into separate isos such that no user may ever need
to actually implement the total aggregate.
This apportionment of isos with additive capabilites might also allow the provider
to delegate the programming of different isos to different subordinates.
