And will it be closed? yes and yes. cdrecord by default closes each session it writes. By default it's single-session. So, without options it does a single session and closes that session - and since it's a single session that closes, it also fixes the CD (writes the Table of Contents) If you want to write multisession, specify the -multi flag. >From looking at the mkisofs man page the answer is yes to the first >guestion.
