Some further information. A resent gnome autobuild failed to run
x-server. Is the error similar ?
See frame 456 - after 113 seconds
http://www.morphix.org/autobuilds/video/morphix-gnome-2006-06-17_0459.mod_basemod-2.6.15-2006-06-17_0015.iso.ogg
http://alextreme.org/autobuilds/morphix-gnome-2006-06-18_0459.xml

I think this caused by a package change in sid.

Previous gnome-autobuilds have run ok including a sarge build:-

These nice instructions by aquatix, are also in the manual,

Could you post more details of the specfic errors. Tested using a real
boot or qemu/vmware ?

There are autobuilds based on stable/sarge ;-
http://morphix.org/autobuilds/mainmod/sarge/
These tend to boot fine,
http://www.morphix.org/autobuilds/video/?M=D
   (NB Autotesting videos have been down for about 10 days - I have
been on holiday and the machine overheated!)

What did not work ?
Tried Morphing-Morphix_0.2 ?

Any specific feedback on how the documentation can be improved will be helpful.

Why not submit your template as a guest build.
http://morphix.org/index.php?option=com_simpleboard&Itemid=78&func=showcat&catid=14
This will be build using sarge and sid and autotested.

Also - just out of interest which base was used ?

Hope this helps,

[Morphix-user] Arrr, and other noises of documentation-related frustration.

[Larry L. <gt...@pr...>]

Dear Morphix-Users's email list,

I've been tooling around with Morphix for a few days now, and I am having=
 not so
much luck.

Here are my requirements:

I have a somewhat special-purpose application in mind.  For various reaso=
ns, I
have to have a debian stable environment, and I have a custom kernel to i=
nstall
(based on the debian sources, of course), but it must be a 2.4.27.

Here are my difficulties:

I have attempted to modify morphix-gnome.xml to produce a debian-stable b=
ased
livecd, as currently that template produces a unstable(or testing?) based=
 image.
 I played around with the package list until I was satisified that essent=
ially
all of the same packages were being installed (some have changed name, so=
me
don't exist in stable, etc), and you may find it here, for your perusal:
http://www.math.gatech.edu/~lindsey/morphix/my-morphix-gnome.xml.gz

I used the instructions found here:
http://aquariusoft.org/page/linux/livecd_howto/

to produce an iso.  Note that at this point I have merely modified the te=
mplate.
 I have not messed with the kernel or my specific software as of yet.  Fo=
llowing
these instructions did produce a bootable iso image, however, one that sp=
ewed
errors about read-only filesystems and a missing user (morphix, or mmorph=
, or
whatever that username is), and which would only reboot itself after a ce=
rtain
point, I assume, because it could not figure out how to start the X serve=
r.

This is only the most recent of several attempts that have ended in failu=
re.

So, I have an observation and a question.

First the observation:  The user documentation for morphix sucks.  I hate=
 to be
so negative, because everything else about the project seems wonderful.  =
The
idea of an easy-to-build livecd is pretty hot.

So here comes the question:  Is anyone willing to help walk me through cr=
eating
such a cd with morphix?  If someone could successfully do that, I might b=
e
willing to help you out by producing some documentation that can be under=
stood
by someone not familiar with the inner workings of the project.

Love,

Larry

Hi All,

Trying to update to the latest mmaker package.

This is requesting I upgrade libglib to libglib2.0-0 (>= 2.10.0). So I
have to upgrade to xserver-xorg-* and remove   xserver-common
 http://www.barwap.com/morphix/morphix-mmaker_upgrade.txt

Anyone done this ? It looks dangerous ?

[Morphix-user] Morphing-Morphix version 0.2

[Brendan M. S. <me...@ba...>]

Hi All,

I am looking at updating Morphix-Morphix, so that there is examples
using some of the newer tools. Also a couple of minor bugs need
fixing.

I have an outline function specification, well more of a list,
detailing the menu options for the new version. I am after other
suggestions for other possible menu options. Feel free to edit the
wiki page :-

It is available in MorphixBase-0.5-pre3.iso:-
/minimod
 MorphixMini-nvidia-6106-k2.6.7.mod

It did take me a while to find this minimodule. Once I understand what

Hey Giulio,

Simple answer: you can't, at least not directly :)

Long answer:
The process of building a module using mmaker consists of running a
debootstrapped bare Debian inside a chroot, thus it is impossible to
access the host filesystem (as that's the whole idea). Thus, without
some nasty tricks you can't have apt install your packages from the host
system.

There are a number of solutions possible:

The easiest would be to simply copy the packages over into the resulting
directory /tmp/libmorphix-bla, chroot into this directory and install
the packages manually. Annoying to automate, however.

Another method would be to mount --bind the directory from the host
system to a directory in the chroot. This way, you would again have
access to your packages inside the chroot. Also hard to automate.

Yet another method is to host your own repository in the host system via
FTP or HTTP. This is slightly more work to set up, but is the best way
to automate the process currently.

A forth method, and one I've been considering (you're not the first to
run into this limitation), is adding a commandline option to mmaker.
You'd give one or more filenames of the packages, mmaker would then
automatically install the packages inside the chroot after it has
processed the template. (mmaker -p /debs/mypackage.deb)

For now you should be able to figure things out. I'll put the
package-option on my todolist for mmaker. In the mean time you might
want to join the morphix-devel list; morphix-user was ment to be for
users of the default Morphix live cds, devel is both for people making
their own live cds as for us developers working on Morphix.

cheers,

Alex

[Morphix-user] Local .deb in main.xml

[G1ul10 <g1...@li...>]

Hi all,
I've a question whose answer I was unable to find in Morphix's FAQ and
wiki. I've home made .deb packages stored in 

/debs

which I can see from my Debian system with the following line
in /etc/apt/sources.list

deb file:/debs ./

I would like to have them added to the main module... what's the
right <repository> statement I've to put in main.xml?

Thanks,

	Giulio.

Sounds like a good idea, I should have used the   mmaker option:-
            -t:     use this temp directory instead of making a new one

Thanks for the feedback, something to add to the next version of
morphing-morphix.

Not really. os-works / os-cillation has (or should have) newer
xfce4-packages than Debian unstable. If their repository isn't
available, then the default xfce4 packages from Debian unstable are used
instead.

Hi Alex,
thank yuou very much for you suggestion. Indeed using
basemod-2.6.15.xml and lightgui.xml from the cvs and with the command

isomaker -b basemod-2.6.15.xml -m lightgui.xml -r
http://www.morphix.org/debian/udeb -p grub-gfxboot-iso-udeb -p
morphix-cdrom-misc-udeb -p morphix-grub-menulist-udeb -p
morphix-iso-grubtheme mylivecd.iso

I was able to to make a  working livecd.

However, during the process I've obtained many warnings like this

W: Couldn't stat source package list http://www.os-works.com
unstable/main Packages
(/var/lib/apt/lists/www.os-works.com_debian_dists_unstable_main_binary-i386_

are they potentially dangerous?

You might have more success when using the templates currently in CVS
(/mmaker/templates), or the ones from the autobuilds. The ones in the
morphix-mmaker package are already reasonably old, I'll package the
latest ones when I get the chance.

Running mmaker within a chroot is interesting. You make be mixing
methods of morphing a cd.

Have a look at Morphing-Morphix, it contains lots of examples. Boot
the cd, from the form the main toolbar menu, selecting
Morphing-Morphix. You can do lots of example Morphing from the cd.

Hope this helps,

[Morphix-user] problem with isomaker (maybe)

[G1ul10 <g1...@li...>]

Hi all,
I'm trying to morph a morphix CD. I've took two config files
from /usr/share/mmaker/templates

mkdir morphing
cd morphing
cp /usr/share/mmaker/templates/basemod-2.6.13.xml basemod.xml
cp /usr/share/mmaker/templates/lightgui.xml lightgui.xml

then I edited  basemod.xml to change the source of knoppix deb
packages (the one in the file did not seem to work) so that now it reads

  <repositorylist>
   <repository type="debian">ftp://ftp.debian.org/debian</repository>
<!--   <repository type="debian">ftp://127.0.0.1/debian</repository>-->
   <repository type="plain">http://www.morphix.org/debian</repository>
<repository
type="plain">http://debian-knoppix.alioth.debian.org</repository>
</repositorylist>

and finally I used

isomaker -b basemod-2.6.13-my.xml -m lightgui.xml \
-r http://www.morphix.org/debian/udeb -p grub-gfxboot-iso-udeb \
-p morphix-cdrom-misc-udeb -p morphix-grub-menulist-udeb \
-p morphix-iso-grubtheme mylivecd.iso

to obtain the iso. When I tested it with

qemu -cdrom mylivecd.iso 

I've got an error:

...
losetup: /dev/cloop: no such device or address
Can't find MORPHIX filesystem, sorry
...

Can someone help, please? 

Notice two things:

1) qemu is properly configurated; indeed I'm able to run the original
morphix iso images

2) I'm doing everything from inside a chroot in the main module of a
MorphixCombined-LightGUI-0.5-pre4.iso

Best,
	G.

I would use cloop-utils as default, although I am note sure this was
the problem.

Does this look for a file size of less the 50 bytes rather than less
than 50k bytes, try:-
SIZE=3D`du -s -k $DIR | awk '{ print  $1}'`

Also I would add bs=3D1k :-
dd if=3D/dev/urandom of=3D$DIR/morphix/files/padding.junk bs=3D1k count=3D$=
SIZE

Personally I ammended mimimod-gen to always produce a junk file of 20K
as it takes up so little space on the compressed minimodule it IMHO
not worth deleting.

Hope this helps,
Brendan

Yes, now if i use my iso with only mainmod, there's no problem.

from the LiveCD

Now when i build minimod using minimod-gen, there's no problem but when i
use this script:
######
DIR=/mnt/sda1/mini-module/test-mini/
MINIMODULE=/mnt/sda1/mini-module/test-mini.mod
#TMP=/mnt/sda1/tmp

SIZE=`du -s $DIR | awk '{ print  $1}'`
: $((DIFF = 50 - $SIZE))
: $((DIFF = 2*DIFF))
if [ $SIZE -lt 50 ] ; then
        dd if=/dev/urandom of=$DIR/morphix/files/padding.junk count=$SIZE
fi
mkisofs -U -R -V "Morphix Mini" -hide-rr-moved -cache-inodes \
-no-bak -pad  $DIR | nice -5 create_compressed_fs - 65536 > $MINIMODULE

rm $DIR/morphix/files/padding.junk
######

...i obtain the same errors

i need to automize minimodule generation, so is difficult for me to use
minimod-gen. I look to source and i can't understand what minimodule-gen
does and i don't

Are you building it from the LiveCD or building it on a different
linux environment ? It looks like the cloop used to build the module
is the wrong version, but the live-cd should have the correct cloop
versions.

Was the default repository on the templates changed from 192.168.0.1
to a valid repository ?

I have not pointed the template directly to Debian to try to encourage
the use of local repositories and reduce the load on Debian servers.

There is a patched version of minimodule-gen on the Morphing-Morphix
CD which includes as file in test-mini/morphix/files/ called
minimodule.junk to make sure the module is above the minimum size.

Either missing mainmodule ? or incorrect cloop version.

In principle, yes. However, you do need to add the /morphix mainmodule
bootscripts to the mainmodule in order to have your livecd do anything.
It won't start any of the usual init[.d|tab] scripts by default.

[Morphix-user] Cloop your linux box and place the mod file into mainmod directory

[Raj S. <ra...@gm...>]

Can i simply copy a working linux box compress it into mod file and but it
into mainmod folder. will this work , coz after all the morphix extracts
this mod and runs the system in this mod itself.

If i can do it this qay then I can virtully make any distro into a live cd
and for any platform.

Try adding a larger file to your minimod (50kb or so). I think Brendan
(bmsleight) also ran into this limitation some time ago: cloop
compression doesn't work properly on very small files...

[Morphix-user] cloop read error

[<p5...@ya...>]

Hi all,
 I'm trying to costumize morphix using morphing-morphix, but when i try to
boot my new image i obtain several errors...
To build main module i exec this command:
mmaker -t /mnt/sda1/tmp -g debian-bootstrap-sid.tgz default.xml \
default-module.mod

To build minimodule i use minimod-gen.
this is my minimod tree:
#ls test-mini/morphix
REDME files loadmod.sh main_module mini_module

for the iso:
isomorph --add main default-module.mod basemod-2.6.12-2005-12-05.iso temp.iso
isomorph --add mini test-mini.mod temp.iso default.iso

and trying my iso on vmware thi is what i obtain:
[...]
cloop: Read error at pos 477 in file <NULL>, 3619 bytes lost.
* Loading Module /cdrom/mainmod/default-module.mod ...
cloop: losetup_file: 2052 blocks, 65536 bytes/block, largest block is
65562 bytes.
cloop: Can't open device read-write
[...]
* Checking for MiniModules on CDROM
cloop: Read error at pos 477 in file <NULL>, 3619 bytes lost.
head: cannot open '/mnt/main/morphix/main_module' for reading: No such
file or directory
* No unioctl found, not applying unionfs minimodule overlaying
* No able to find /mnt/mini/mod2/morphix/loadmod.sh, continuing
[..]


anybody has any idea?
(all binaries and script that i use are taken from morphing-morphix)

tnx

I like this idea too.

Perhaps Qemu ??.
