Release ISO images have broken RockRidge data

[Eugene Grosbein]

Hi!

Release ISO images located at ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/ISO-IMAGES/
were generated with mkisofs until switch to makefs. For example,
ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/ISO-IMAGES/8.2/FreeBSD-8.2-RELEASE-amd64-livefs.iso
was generated with mkisofs and has correct RockRidge extended attributes.

# isoinfo -d -R -i FreeBSD-8.2-RELEASE-amd64-livefs.iso

Volume id: FreeBSD_LiveFS

This image may be unrolled correctly with respect to hardlinks using xorriso command from ports:

# xorriso -for_backup -load volid \* -indev ../FreeBSD-8.2-RELEASE-amd64-livefs.iso  -osirrox on -- -extract / livefs -rollback_end

Newer images (8.3 and later) were generated using makefs that seem to produce incorrect RockRidge data:

# isoinfo -d -R -i FreeBSD-8.4-BETA1-amd64-livefs.iso | grep id
System id: NetBSD
Volume id: FREEBSD_LIVEFS
Volume set id:

Eltorito validation header:
    Hid 1

Same xorriso command produces tons of following error messages and unrolls the image
without respect  to hardlinkg increasing size in nearly 3 times:

libisofs: WARNING : Invalid TF entry
Caused by: Wrong or damaged RR entry

bsdtar from 8.3-STABLE shows lots of errors too, while extracting FreeBSD-8.4-BETA1-amd64-livefs.iso
mdconfig breaks hardlinks too.

Is it possible to unroll this image respecting hardlinks?
