| From: Tim <ignored_mailbox@xxxxxxxxxxxx> | I am curious why there's a need to do this externally. Both mkisofs and | cdrecord have "padding" options. Do they not do the trick? Good question. I think that the cdrecord padsize= option can be used. It is pretty hard to make out what it does from the man page. The padding stuff in growisofs will not work with a .iso file. It only works when creating a new .iso (if then). In any case, I actually burn with k3b these days and I don't remember that it has a way of requesting padding. So I use isopad before k3b. All this is based on superstition, so there may well be better approaches.
