linaro-media-create stops bluetooth during while building SD card

[Angus Ainslie]

While creating an SD card the bluetooth gets stopped. This also stops bluetooth in the host.

Guess this happens because the bluez service is restarted while
creating the SD card.

We could fix this at the package side, but I believe the proper fix
would be at linaro-image-tools, in a way it could avoid services to
run while installing/upgrading the packages (like linking upstart to
/bin/true and such).

Do you mean that we should do
    ln -s /bin/true /sbin/start
on the host system before we start installing packages to the chroot?

Is it a good idea for l-m-c to try to change the behaviour of the packages? I do agree that it shouldn't restart services on the host though since we target a chroot.

we should prevent daemons to start in the chroot:
echo "exit 101" > usr/sbin/policy-rc.d
chmod a+x usr/sbin/policy-rc.d

it's usually done like that when you bootstrap a debian/ubuntu chroot.
All rc.d operations are disabled by a policy-rc.d script.
i.e. man cdebootstrap

Yes, the less we interfere at the host, the better.

Guess we should just do it in a similar way as done by cdebootstrap.
Just be sure to revert all of that as the last step.

I'm getting another error while writing image to sd card with l-m-c: http://paste.ubuntu.com/815093/. My host is lucid.

That looks like a problem with the ubuntu-omap4-extras-config package:

Setting up ubuntu-omap4-extras-config (1.30) ...
start: Unknown job: ubuntu-omap4-extras-config
invoke-rc.d: initscript ubuntu-omap4-extras-config, action "start" failed.

It's basically the same issue as described initially by this bug, but
as the host system didn't have the same job available for upstart, it
failed when trying to start it at the chroot.

I just tested the solution in comment #3 and it works fine. The SD is generated and then it boots. I don't know if there is any negative side effect with this solution.

For the record i uncompressed the tar.gz file system, created a policy-rc.d and compressed it again.

[Miguel Angel Cabrera (mad-aluche)]

By the way my problem was the same that the one in comment #5

[Miguel Angel Cabrera (mad-aluche)]

I just installed openssh-server and i noticed that is necessary to remove policy-rc.d from the installed filesystem because it is not necessary anymore.

[Julien Dehaese (jeseahed)]

I had the same issue as posted in comment #5 on a debian amd64 host and followed the same path as Miguel's (comment #8) and I confirm it works.
