Thanks for testing.

I see the common theme in all these cases: a file should be there in
rootdir but isn't.

I also see that you are using 'find'.  Does the file show if you are
using 'ls'?

 ls /tmp/live-net-remaster-pro1Wm/chroot/usr/share/doc/ | grep xorg
 ls -d /tmp/live-net-remaster-pro1Wm/chroot/usr/share/doc/xorg

Could you please do a strace of 'find'

  strace -v -o /tmp/strace find /tmp/live-net-remaster-pro1Wm/chroot/usr/share/doc/ -maxdepth 1 -name 'xorg*'

And send the resulting trace in /tmp/strace?

Thanks,
Miklos
