So you want to use CD-Rs or CD-RWs to transport the image parts to a second computer.
You can use the split(1) program to split the ISO image into appropriately sized parts.
Mkisofs does the very same but with larger (fixed) fragment sizes.
You probably have to create iso-filesystems, each containing one fragment-file to keep
the
fragment sizes exact. (I had sometimes problems when reading raw data from CD-Rs, the
last sectors
probably the next after last with user data produced read errors. So I don't know if
you can
realiably read the raw fragment data off the CD.)
Remember to merge (cat(1)) the parts before writing a DVD or mounting it via the loop
device! ;-)
If you want to make several different images, each fitting onto a CD, you, of course,
have to choose
yourself which dirs/files you want to put onto the different volumes. ;-))
Kind regards
