From the Notes-section in "man growisofs" :
NOTES
If executed under sudo(8) growisofs refuses to start. This is done for
the following reason. Naturally growisofs has to access the data set to
be recorded to DVD media, either indirectly by letting mkisofs generate
ISO9660 layout on-the-fly or directly if a pre-mastered image is to be
recorded. Being executed under sudo(8), growisofs effectively grants
sudoers read access to any file in the file system. The situation is
intensified by the fact that growisofs parses MKISOFS environment vari-
able in order to determine alternative path to mkisofs executable
image. This means that being executed under sudo(8), growisofs effec-
tively grants sudoers right to execute program of their choice with
elevated privileges. If you for any reason still find the above accept-
able and are willing to take the consequences, then consider running
following wrapper script under sudo(8) in place for real growisofs
binary.
#!/bin/ksh
unset SUDO_COMMAND
export MKISOFS=/path/to/trusted/mkisofs
exec growisofs "$@"
But note that the recommended alternative to the above "workaround" is
actually to install growisofs set-root-uid, in which case it will drop
privileges prior accessing data or executing mkisofs in order to pre-
clude unauthorized access to the data.
I have to start k3b with "kdesu k3b", not just "sudo". Then it finds growisofs
and it all works.
