[fedora-arm] Customize Fedora 21 ISO

[Brooks Hu]

Thanks Dennis.

I did following experiment:

Mounted ISO onto a local directory, changed to the directory, did nothing,
run "createrepo --update .", but I found the files under repodata changed,
including the checksum in filename. Is that expected? I suppose they
shouldn't be changed.

I am readying the manual of pungi.

One more question: do you have any good links about customizing a ISO? I
found a few pages, but they seem not to work.

Regards,
Brooks
