[Pkg-libvirt-maintainers] Bug#928646: libguestfs-tools: virt-builder --ssh-inject does not accept public keys with cardno:NNNN

[Elena ``of Valhalla'']

Package: libguestfs-tools
Version: 1:1.40.2-2
Severity: normal
Tags: upstream

Dear Maintainer,

I tried to create an image using ``virt-builder [various parameters]
--ssh-inject root:string:"$(ssh-add -L)"`` and a key whose secret part
is saved on a smartcard, and got an error:

   virt-builder: error: invalid ssh-inject selector ‘string:ssh-rsa
   AAAA[my public key] cardno:XXXXXXXXXXXX; see the man page

I tried again by copypasting the string itself and manually changing the
last bit to a fake user at host and it worked.

I think that keys in the former format should be supported as well.

Thanks,
