The brute-force method is to use dd to write each diskette's contents
to the hard disk, then copy them back to another diskette, also with
dd.

Installp uses backup format, like updatep.  I've had good luck using
restore to read the files from diskette into a directory hierarchy on
hard disk, then use backup to collect the hierarchy into a single file
in hard disk.  Updatep can use such a file to apply an update, given a
command line like

updatep -aci -d filename

The same approach will, very probably, work with installp.  Read the
diskettes once, create a single archive file, and transfer it to other
hosts by FTP.
