    Hello
    
    Disks keep getting bigger :-(
    
    It is straight forward to split up a large disk in to CD-R size chunks but
    am I missing something painfully obvious for a reconstruction of a disk from
    said CD-Rs? I assume you need a large holding disk in order to
    
    cat img.1 img.2 img.3 etc etc > /dev/disk-whatever (or using | dd
    of=/dev/disk and options to maintain blocksizes, etc)
    
    [gzip, zcat, etc could be used to reduce the image sizes but becomes
    somewhat hard to predict with regard to compressibility without a dry-run]
    
    Is there any easy way to append from individual CDs to a device file?
    
    Feel free to point out the painfully obvious and any hints as to what to do
    as disks get way too big ;-)
    
    Cheers
    Neil
