growisofs should have a method for padding
The 2.6 kernel's CD/DVD driver has the unfortunate propensity to read
ahead past the end of a CD/DVD. It then reports an error, even if the
actual read request was completely legitimate. See, for example,
<https://www.redhat.com/archives/fedora-list/2005-March/msg02774.html>
The conventional work-around is to always pad when writing a CD/DVD.
Ugly, but true. (I agree that this isn't the correct fix, but the
problem has not been fixed in a year, so it isn't going away soon.)
See, for example,
<https://www.redhat.com/archives/fedora-list/2005-March/msg03201.html>
growisofs can burn a pre-mastered image. It would be nice if there was a
way to ask it to add to this burn a specified amount of padding.
The only way I know of accomplishing it is to actually pad the image
file. Not very elegant or convenient. (It breaks any signature too.)
One suggestion: implement -pad and -padsize options.
When I try one of these, I get an error message:
/usr/bin/growisofs: no mkisofs options are permitted with =, aborting...
Not very clear. Essentially, it means that some options are not
supported when growisofs is doing all the work itself.
