[libvirt] virt-install and custom distros

[Kay Williams <kwilliams renditionsoftware com>]

We have an application that builds custom distributions based on RHEL, CentOS or 
Fedora.  We would like to install these over the network using virt-install, but 
we've run into an issue with the distro check logic. Specifically, virt-install 
fails unless it finds a string "Red Hat Enterprise Linux", "Fedora"  or "CentOS" 
within the family field of the .treeinfo file.

Our application currently sets the family field to the user-provided distro name 
(see below).  We have avoided using the base distro name given trademark concerns.

    [general]
    family = <user provided value>
    variant = <user provided value>

We can get virt-install to pass the distro check by setting the family name to 
one of the accepted values, e.g.

    [general]
    family = Fedora
    variant = [user provided distro name]

Is this the expected/desired use for the family and variant fields?  Or is there 
another approach we should consider?

Thanks,
Kay
