The traditional answer would be to have a separate download which
contains only the BASE packages and whatever is needed to install,
such as UNZIP and the package manager :-) I would still like to
hear what the largest packages in FDI-USB are and which packages
of which size from Mateusz' 500 MB repository are still missing.

Having a separate download would make it easy for people to either
enjoy ALL Mateusz' packages on a 500+ MB size stick without having
to worry about DOS networking drivers (do you include ANY yet?) and
at the same time make things quick and easy for others who simply
want a basic install of DOS with a quick download :-)

Hm? Are the "obscures" large? Are FPC, FreeBasic, DJGPP obscure?

Not really. Yet I agree that it is better to load FDAPM early ;-)

You could make it simpler: If there is enough space to install (make
a base / all distinction) without deleting anything, be happy. If you
have less space, warn the user: They MIGHT be able to install stuff,
because the install will overwrite some old versions with newer ones,
but they continue at own risk. Give the user a rough idea of free size.

Can we assume that stuff is moved to backups, instead of adding backup
size to the amount of already used disk space?

I had the impression that you wanted to avoid individual package choices
to keep the install simple? Of course the package manager can always be
smart and ponder how much space is consumed by installing [list of some
packages] but for the moment, I guess knowing how large base / full are
should be enough to get a rough idea in the installer, not in fdnpkg :-)

Yep. And maybe have a separate BASE-only download: Less disk size used
and less download bandwidth used. Plus people can always install extra
stuff later using the package manager. Either by feeding it package ZIP
files or by getting DOS networking to work.

A classic tool for your errorlevel based disk space usage checks ;-)

Cheers, Eric



PS: It is a bit weird that the current image has to overwrite the whole
stick, which often is a lot larger than 256 MB. How about alternatives
that you copy to already FAT formatted sticks and a tool to SYS & MBR?
I know, FAT is less popular today, but this would be nice for those who
do not want to mess up stick partitions or do not know how to redo them.
