Ubuntu karmic Appliance

[tobru]

Hi,

I tried to create a Ubuntu karmic (beta!) appliance, but it fails with the following output:

initialize VE 90000
package 'initramfs-tools' depends on exclusion ' module-init-tools'
package 'initramfs-tools' depends on exclusion ' module-init-tools'

Has anyone an idea what I can do to get this working?

Thanks!

Regards,
Tobias

Ok, found the answer:
Added karmic to the following line in DAP.pm (line 484):

elsif($suite eq 'intrepid' || $suite eq 'jaunty' || $suite eq 'karmic')

Thanks for this great tool DAB!!

The above solution didn't do the job for me. Here's my patch:

Many thank for the patch. I tried it, but i failed - it still starts mountall and that fails. Did you delete /etc/init/mountall.conf?

Hi,

sorry - I should have mentioned that it might take two tries to get the appliance to startup successfully for the first time.

The script modifies /etc/init/mountall.conf to skip running mountall. During the first container start, /etc/init/mountall.conf might run before /etc/init/openvz.conf and thus unmodified which will cause the container startup to fail at least partly.

My appliance mostly works now, though I still have some problems connected to upstart:

• initctl emit ... does not seem to work (blocks)
• services that should start automatically don't start (such as networking and portmap, that's whay I had to mention them explicitly in the script section of /etc/init/openvz.conf).

Once the container is up, it seems to work fine. I'm using it as a remote desktop session over NX.

That new upstart is quite incompatible with containers. I tried to modify the mountall.conf, but it seems I can't get the dependencies working (networking does not start, ...). I already saw your hacks, but that is IMO the wrong way.
