CentOS docs - Mar 2007 - Edit permissions and CD to DVD procedure

Wiki name PhilSchaffner.  I would like to work on the following pages:

TipsAndTricks/CreatingUpdateMedia - new page
        How to create CD/DVD update media and use to update CentOS

HowTos/BuildPackages - new page
        How to set up an end-user environment to build RPM packages

HowTos/CreateLocalRepos - new page
	How to create and maintain local repo[s] for your custom packages

MigrationGuide - existing page
        Add/modify content from C5 testing, Migration/5, and C3 FAQ "How
        do I migrate a system from WBEL-3 (White Box Enterprise Linux)
        to CentOS 3?"

FAQ/CentOS4 - existing page
        Add FAQ entry on "How do I migrate from an ELx-based distro to
        CentOS4" with link to MigrationGuide

Would also like to see some content in TipsAndTricks/CDtoDVDMedia.  My
attempts to do this have failed to produce a usable DVD.  The firewall
at work precludes using BitTorrent to download anything so it is hard to
get the DVD iso image.  Would be glad to help edit that page also if
someone can provide a hint.  Tried to follow the advice in the thread

http://lists.centos.org/pipermail/centos-docs/2006-September/000016.html

that was supposed to result in the above page being filled in.  I can
produce a bootable DVD using the procedure and the referenced script
mkdvdiso.sh (after fixing a syntax error) but attempts to use it to
install die with a complaint about not being able to find the 2nd CD -
at least for the C5 beta.   Has anybody made this work?

This is already handled in
<http://wiki.centos.org/TipsAndTricks/YumAndRPM> - maybe better add to
that page?

Okay, I thought we had something like that already. We don't. Looks like
a good idea to me.

Can you talk to smooge about that? I know that he has something similar
in mind, I just want to keep you from doubling content or effort.

Sure. 

If we can clarify the above stuff, I'll give you access rights to those
pages.

Cheers,

I would like editing rights on this page also.

Something like:

Some users with limited bandwidth may want to use "sneakernet" to
update
from removable media such as CD or DVD.  To create such a CD/DVD
(currently about 1.1 GB for i386 implies DVD) containing all the updates
follow this procedure.

For example, for the i386 updates, the top level of the DVD should have
the contents of the updates/i386 directory:  headers  repodata  RPMS

With k3b one can create this DVD quite easily by selecting "New Data DVD
Project", navigating to a previously-downloaded copy (or local mirror)
of the updates for the desired arch, dragging the 3 directories to the
DVD window, and selecting "Burn".

For CentOS4 a CentOS-Media.repo file already exists in /etc/yum.repos.d.
Mount the update DVD and do:

# yum --disablerepo=\* --enablerepo=c4-media update

New media can be created when enough updates, or important enough
updates, come out to justify the effort.

Works for me.

We already had some interchange on the QA-list the page I edited:
http://wiki.centos.org/Migration/5

http://lists.centos.org/mailman/private/centos-qa/2007-March/000309.html

Would be glad to coordinate further to avoid any duplication.

Let me know if anything remains unclear.

Thanks,

Sorry for the self-reply - never got a response to this part of the
original query, and I see we have another potential contributor
interested in this area - Wojtek Pilorz.  Have done some more work on
the mkdvdiso.sh script and can now make it work for CD ISO images, but
not yet from the OS unpacked tree - builds a DVD that boots, but is not
recognized as CentOS install media - I'm missing something about
the .diskinfo file.  Also added some sanity checks.
