First of all keep in mind that I myself don't have access to an HP-UX system and can't personally verify the HP-UX code posted on my page. In general HP's goal is to deliver dvd+rw-tools on some Free Software Add-ons for HP-UX CD. 5.14.x is unlikely to be the version which will appear on that CD, but is an experimental public release. Idea is to understand better what are users' expectations and what's optimal thing to do.

In order to generate an increment to an isofs volume, mkisofs has to be instructed where to find the volume to be grown. On other supported OSes, it's elegantly done by passing opened file descriptor to mkisofs. HP-UX on the other hand doesn't support /dev/fd/N and we have to find another way to achieve that. There're several options: - pass so called BTL address to mkisofs, where BTL stands for Bus, Target, LUN, which identifies a SCSI unit. This requires mkisofs to be installed set-root-uid and is not exactly desired. - patch mkisofs to interpret passed arguments in a way which makes it possible to pass opened file descriptor, in which case mkisofs won't require any extra privileges whatsoever (and might as well reside on user's $PATH if [s]he wishes so). This is what mentioned code snippet is about. As in 5.14 tar-ball, growisofs expects mkisofs to be patched with proposed patch (you can copy-n-paste text between "#elif 0" and "#endif" into separate file and apply the patch in mkisofs source tree). This is most likely how it will be implemented on the HP-UX CD. But you're free to change that by replacing "#if 0" with "#if 1," in which case growisofs will pass BTL address instead of opened file descriptor. Once again, only growing volumes is affected by this, i.e. growisofs -M. growisofs -Z works "out of the box." A. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
