Actually I was always talking about the permissions/timestamp on the test
directory "dir1", these were incorrect even when the iso was created with
mkisofs a42.
But I was not saying this was a mkisofs bug, since if I transferred the very
same iso image on a RHEL3 system, it would then see "dir1" with correct
data.

Ok.
So this would explain why, given 1 iso image, RHEL3 sees things fine, while
RHEL5 does not.

I can confirm that with the patch the permissions of "dir1" are ok even
without "-find".
Thanks.
