Possibly satisfactory for those with fast connexions and large

It would be better to have all the updates since the last release, to 
keep a more stable base.  If packages are available as incremental 
updates since the last release, the size of such updates will be 
considerably smaller.  That way we could potentially produce update CDs 
at any time, from an incremental update repository.

Once (when I had more limited space on my main partition) I removed all 
unwanted language files - not counting language-specific rpms, which 
were not installed - and reduced the total space used by over 15%.
In the space still used, were all system-wide configuration files and 
log files, as well as various temporary files.  So considering that 
there are many language-specific rpms, I would't be surprised if there 
were 20% less space for applications on the all-languages CD.

One could always download the update repositories, which would be the 
Rpmdrake could be modified to facilitate this.
However very few users would have close to all these packages installed 
- and certainly not many bandwidth-limited users, as to do so would 
require a very large amount of disk space.

On reflection, it would probably be much more useful to have incremental 
updates for individual packages, for the files changed in the package 
since the last distro release.
Typically much less than 10% of the size of the full package; probably 
more like 1%.

Another post mentioned that all the updates from one release to the next 
accumulated to 700M, or the size of a CD.  It would be surprising if a 
typical installation used more than 10% of the packages available, thus 
not more than 70M, and a typical bandwidth-limited installation would be 
much smaller.
So with incremental update rpms, we are talking about 7M or less for a 
typical installation over 6 months, or about 1M/month, and much less for 
a bandwidth limited installation.
Thus incremental updates seems to be a better solution for most 
bandwidth limited users.
However CDs of updates could always be done on an ad hoc basis.

Another point : such a disc would only be up to date (or almost) at the 
moment of its creation.  2 days later, it would almost assuredly be
