It looks weird, yes.
But to my knowledge this command copies the
first 64 kB from the previous session to the
If those 64 kB contain the superblock of the
filesystem and if this superblock is relocatable

Maybe the UDF superblock is located in the
first 32 kB ?
Whatever, Gregoire reports, the closed DVD+R

It would be interesting to make this experiment.
Gregoire did not explicitely confirm that the
result of growisofs -dvd-compat -Z does work
But i assume he would have reported the contrary
if that was the fact.
Have a nice day :)
