ReactOS Hybrid CDs

[Hermès BÉLUSCA - MAÏTO]

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.

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.

IIRC, that was because I put a folder "Build Environment" or even
"ReactOS Build Environment" on the CD. Usual ISO9660 didn't like the
spaces or the length of the name whereas ISO9660:1999 (as supported by
that mkisofs version) had no problems.
I leave that for you to find out ;)
If cdmake can properly create an ISO with all required extra
directories, we're good to go.

I will retest. But iirc we have a switch to enable " punctuation marks other
than underscores in names and extensions" (option -m) that we use for
building the livecd (because we add some shortcut files with long names with
spaces and such).

Hi !
We are ok concerning the long file names with spaces, see picture for more
details. So Colin, you're good to go!! (A last note, we would need to fix
the autorun.inf file so that the welcome.exe file is correctly started...)
Also: we *STILL* have this date and time problem in CDMAKE !!!! so the fix
http://svn.reactos.org/svn/reactos?view=revision&revision=66029 is only part
of the real fix. Hervé, could you please have a look into that? Thanks in
advance!
Cheers,
Hermès.
