this ISO images misses libhandle.so.0 and libattr.so.0 in rescue mode,
so xfsrestore fails due to these libraries missing.
I have a workaround: mke2fs a floppy, mount it and copy (cp -p)
/sbin/xfsrestore, /lib/libattr.so.0 and /lib/libhandle.0 to it. Don't
forget to umount before ejecting.
When being in rescue mode booted off the CD or its bootnet.img and
network, mount the floppy to /fl and call xfsrestore in this way:
LD_LIBRARY_PATH=/fl /fl/xfsrestore -r - .
XFS developers: please make sure xfsrestore is working on the next ISO.
It is very handy for disaster recovery oder just for cloning systems.
