Re: [ros-dev] ReactOS Hybrid CDs

I would like to add few notes:

 

- this is something that replaces the hand-made method used previously for
the special Chemnitzer Linux Tage ReactOS CDs that were built: see
http://svn.reactos.org/svn/reactos/branches/ros-branch-0_3_16-clt2014/reacto
s/make_hybridcd.cmd?revision=62438
<http://svn.reactos.org/svn/reactos/branches/ros-branch-0_3_16-clt2014/react
os/make_hybridcd.cmd?revision=62438&view=co&pathrev=62438>
&view=co&pathrev=62438 for example (code © Colin Finck).

 

- @ Colin: in your script is mentioned: “Our cdmake doesn't support creating
an ISO9660:1999 filesystem, which is important for a universally usable
disc.” : is this remark still valid or not?

 

- Finally, I need somebody who can test whether hybrid cds can be built with
RosBE under Linux, and whether they work or not (concerning Windows, the
test is already done ;) ). Thank you in advance!

 

Cheers,

H.

Hi all !

 

Our build system is now able to build so-called “hybrid cds” . What are
they?

They are boot+live-cd all-in-one. In addition it is now possible with them
to load the live cd as a ramdisk. For that the contents of the bootcd is
placed into a bootcd/ directory, the contents of the livecd is placed into a
livecd/ directory, and the livecd image itself is also included (this is the
one that is used for livecd ramdisk). You can notice that makes a lot of
redundancy, but it’s the best thing I could do for now. The best way would
be to build some kind of flat HDD image that is used as the livecd ramdisk
(and never use the livecd with reads from the cd as we currently do…) .

Anyways.

So here it is !

In addition you can add extra custom files via the build process: just place
your files into a <your_ROS_source>/modules/hybridcd_extras/ directory (this
directory doesn’t exist by default, it’s up to you to create and populate
it; I think it’s better to create a directory somewhere else and then add a
symlink “hybridcd_extras” to this directory, inside the modules/ directory,
as you already do with rosapps and rostests).

After that you configure a build, build the host-tools and then ninja
hybridcd !!

If then you need to change the custom files, do it and then reconfigure a
build with the “cmake .” command (when you’re inside
<your_ROS_builddir>/reactos/ ) so that cmake can build again the list of
files to be included into the hybridcd.

 

See https://jira.reactos.org/browse/CORE-9069 for few more details.

 

Cheers,

Hermès.
