How about using a vanilla (jeos-like) template, but then running
a small shell script for the role in question?

Here's what I do at the moment (later I might rip out the home
directory sharing):

    case $GUEST_DISTRO in
    ubuntu) verop="-r";;
    centos) verop="-R";;
    esac

    # Share this user's home directory with the virtual machine (!)
    # This only works in ubuntu for now, centos lacks that option
    # (Later, must also specify --bdir $HOME to lxc-start-ephemeral.)
    sudo lxc-create -t $GUEST_DISTRO -n $HOSTNAME -- $verop
$GUEST_VERSION --bindhome $LOGNAME

    # Install slaves on virtual machine, making use of the fact that $HOME is
    # mounted for this same user inside the container, and hoping that
$TOP is in $HOME.
    # Need working network, so can't just do 'lxc-start cmd'
    sudo lxc-start -n $HOSTNAME -d
    lxc-ssh $HOSTNAME sh $SRC/slave.sh install
    sudo lxc-stop -n $HOSTNAME

where lxc-ssh is the script I posted earlier; I'll attach my current version.
