Hi, The explanation for why volname returned CDROM is that is apparently the default volume label when none is specified (which wasn't in the first session). I specified volly on a later session but volname and vol_id (which someone else suggested) appear to not be multi-session aware and

xorriso does not rely on ECMA-168 but on ECMA-119 plus some SUSP based extensions like Rock Ridge. Afaik the mkisofs runs of growisofs do not refer to ECMA-168 either. Yes, today I perused ECMA-168 and realized it specifies a form of layout different than what my burnt discs conform to (i.e.

Hi, growisofs's CD001 That's actually mkisofs's CD001. growisofs -M examines media TOC resp. the ECMA-119 PVD in order to get the parameters for a run of mkisofs -C . growisofs then starts mkisofs and writes its output to the media. In case of overwriteable media it finally copies the Volume
