Ovirt devel - Dec 2008 - cobbler import of a repo with only noarch packages in it

I'm trying to do a cobbler import of a directory structure that only has 
noarch packages in it.  I'm using the import to create a minimal pxe boot 
environment without needing to mirror all of the packages (we just use 
external repos for the packages)

However, when I try to do a cobbler import of a directory structure that 
only contains noarch packages I get the following error:
> + cobbler import --name=Fedora-10 --arch=x86_64
--path=/var/www/cobbler/ks_mirror/Fedora-10-x86_64

I know in the past we were able to import a directory structure with only 
noarch packages and still specify an arch (x86_64 or i386) and it didn't 
fail like above.  Is this a recent change or restriction?  Should we just 
add a single arch specific package to the directory structure to get 
around this?

Thanks,

Perry

So, for those of you using the 0.96 release or building new appliances 
from the development repositories it appears that a new version of cobbler 
in Fedora has broken the ovirt-appliance.

I've posted the above question to the cobbler mailing list to find out if 
this was an intended change or something that recently broke in cobbler. 
Hopefully it is the latter and an update to the cobbler package will fix 
this.  The alternative is that we need to change the appliance build 
procedure to account for this change and we'll have to do a 0.96-2 release 
to fix this.

Thanks,

Perry

What version of cobbler are you running?  I know there were a lot of
changes to the import stuff for debian recently, including how it detected
the arch from the tree automatically, it's possible if you're running a
newer version that functionality may have been broken inadvertently.

I'm running 1.4.0-2 and I think I found the problem... You're right it
is
with the arch detection.  Even though I pass --arch to the cobbler import 
manually, it still tries to verify the arch by looking specifically at the 
kernel-headers package located in the path that you are importing from. 
Problem is, our minimal tree didn't even have kernel-headers in it.

To fix the problem I'm just going to add kernel-headers package into our 
tree.  That seems to work.

Thanks,

Perry

It seems you want "cobbler repo add" and not "import", as
you're talking
more about a noarch repo than an install tree.   I don't see how you 
could get an installable distribution with just noarch packages :)

Import is for install trees, which can also be used as repos, yes.

But repos are not == install trees.

Does that make sense or did I miss something?

If you're doing something really simple "cobbler distro add" alone
might
suffice, though I'd like to understand a little more about the use case 
to say for sure.
