[mdlug] Burning Blu-Ray Disks

[A. Zimmer]

Hello,

I just got a blu-ray disk burner for the purpose of making archival
backups of various files.  To burn BDR disks, I have been creating an
empty UDF file, filling it up with the desired files, and then burning
the filled UDF file with growisofs.

This process, which works very well, is described in the following link:

However, I would like to avoid the necessity of first creating an
intermediate UDF file.  I would like to burn directly from already
existing files.

After some searching, I found a method that uses mkisofs with
growisofs to burn directly files without the need to first create
a UDF intermediary.  The basic command is as follows:

growisofs -dvd-compat -udf -iso-level 3 -Z /dev/scd0 -J -R /path/to/data

The switch "-iso-level 3" allows for a file size that exceeds the
usual ISO limit of 4G.

My question is simple: Does this command work?

For me, because the cost of blu-ray media is relatively high,
I cannot afford to waste valuable BDR disks in experimentation
(I wasted quite a few already).

Does anyone on this list have direct experience using this particular
method?  Before I proceed, I would like a verification that the
command is sound and works as intended.

Also, I am not interested in using any of the burning GUIs that are
available for KDE, Gnome, and others.  For me, it's the command line
or nothing at all.
