That is correct! 'mount -o session=N ...' is not applicable to DVD+RW (nor to DVD-RW in Restricted Overwrite or DVD-RAM). It's applicable only to [growisofs +] DVD+R, DVD-R and DVD-RW in Sequential mode [with limitation discussed earlier], as well as to CD-R and CD-RW. It's possible to access DVD+RW intermediate "sessions" with 'mount -o sbsector=XXXX ...', but it's too boring as you have to write down superblock addresses. > - no platform independent accesss to the backup No. > So I'll continue to use my modified mkisofs, but I won't argue > for its inclusion in mainline mkisofs unless other users also > find it useful. The functionality is useful IMO, but the gut-feeling is that it needs further consideration. E.g. should hard-link counts in RR be adjusted? On the other hand hardlink counters are actually meaningless [at least] in Linux isofs context. Indeed! Given the link count how do you identify other entries in directory which point to the same data chunk? By comparing i-nodes, right? But [as discussed on my DVD+RW page] Linux isofs i-nodes are offsets of corresponding directry entries. So that even if we have file1 hard-linked to file2, we can't tell that they actually are.
