Our kernel does in fact include the "sg" module. However, it is
considered "legacy" [0] and udev intentionally does not autoload it
[1]. If I understand correctly it should not be hard to replace it's
use. Otherwise, you wight want to add to a README or something that
this module must be loaded (as I guess most people are not aware of
this issue).

Out of interest: does the current version of cdrecord always, or at
least in most cases, require this module to function, or is it only
for some pieces of hardware or some functionality?

If this module is wanted by a majority of cdrecord users, then you
might want to simply install a file
"/usr/lib/modules-load.d/cdrecord.conf" containing the string "sg".
That will load the module on boot for anyone with cdrecord installed.
For more details see [2].

The module-load.d directory is supported by us, as well as all distros
using systemd. So Jörg, you might consider including this upstream, if
it is the sg module is really needed.

Cheers,

Tom
