Pls have a review of my media

[Kun Huang]

Hi, all

Now I have some work with anaconda on different media (usb/iso), and also
have some questions, please have a review.

My target: have a directory contains kinds of data could be used to
generate a bootable iso (by mkisofs) and be copied to usb drive as
boot-install usb.

And I have one test case could work:

/images/install.img     # stage2 contains anaconda codes
/isolinux/...                # use for booting in iso case
/syslinux/...               # use for booting in usb case
/os/xxx.iso                # a directory contains an ISO image
/repo/*.rpm                # my own repo
node.ks                     # kickstart which uses /repo/*.rpm as
additional repo for packages
/Packages/*.rpm        # this directory and repodata/ below is standard
repo in Centos6.4
/repodata/
.discinfo                    # these two are used in iso case
.treeinfo

this case works for my cases: in iso case, it boots by isolinux, and
install @core in /Packages; and in usb case, it boots by syslinux and
install @core packages from /os/*.iso.

Now my problem is that the /os/xxx.iso and /Packages&/repodata are
duplicated actually. I tried use /os/xx.iso and repo=cdrom:/os but failed
with un-catched exception "nonetype has no attribute 'format' "

Now before further testing on repo=cdrom:/os I have several questions:

(my anaconda version is 13.21.195 )
1. will anaconda find *.iso under /os in my ISO image by repo=cdrom:/os?
2. are there more better or more common solutions for my target?

Thanks for any reply
