So I did some testing and NetBSD's isos, which are generated much the same way as FreeBSD's , have the same issue . # xorriso -for_backup -load volid \* -indev ../NetBSD-6.1_RC2-amd64.iso -osirrox on -- -extract / netbsd -rollback_en ....... libisofs: NOTE : > Caused by: Wrong or damaged RR entry libisofs: WARNING : Invalid TF entry libisofs: NOTE : > Caused by: Wrong or damaged RR entry libisofs: WARNING : Invalid TF entry libisofs: NOTE : > Caused by: Wrong or damaged RR entry xorriso : UPDATE : 2004 nodes read in 1 seconds libisofs: WARNING : Found hidden El-Torito image. Its size could not be figure out, so image modify or boot image patching may lead to bad results. xorriso : NOTE : Detected El-Torito boot information which currently is set to be discarded Drive current: -indev '../NetBSD-6.1_RC2-amd64.iso' Media current: stdio file, overwriteable Media status : is written , is appendable Boot record : El Torito Media summary: 1 session, 169279 data blocks, 331m data, 194g free Volume id : 'NETBSD_61_RC2' Copying of file objects from ISO image to disk filesystem is: Enabled xorriso : UPDATE : 16 files restored ( 97911k) in 1 seconds , 63.7xD xorriso : UPDATE : 22 files restored ( 173.5m) in 2 seconds , 52.2xD xorriso : UPDATE : 30 files restored ( 252.6m) in 3 seconds , 53.3xD xorriso : UPDATE : 458 files restored ( 297.2m) in 4 seconds , 33.8xD xorriso : UPDATE : 1486 files restored ( 328.4m) in 5 seconds = 50.0xD Extracted from ISO image: file '/'='/opt/home/XXXX/Storage/extract/netbsd' Also for what its worth, tar does work at extracting an iso as well # tar -zxvf ../FreeBSD-7.4-RELEASE-i386-disc1.iso -C out x . x 7.4-RELEASE x 7.4-RELEASE/base x 7.4-RELEASE/catpages x 7.4-RELEASE/manpages x 7.4-RELEASE/games x 7.4-RELEASE/proflibs x 7.4-RELEASE/dict x 7.4-RELEASE/info x 7.4-RELEASE/doc x 7.4-RELEASE/kernels x 7.4-RELEASE/ports x 7.4-RELEASE/src x floppies x boot x boot/zfs x boot/firmware x boot/kernel x boot/modules x boot/defaults x packages x packages/All x packages/converters x packages/devel x packages/gnome x packages/emulators x packages/linux ...... So , what issues does this cause ?
