[Libguestfs] guestmount -i and xattrs

I tried to run chcon to set SELinux labels on a guestmounted dir and got: chcon: failed to change context of `authorized_keys' to `system_u:object_r:ssh_home_t:s0': Operation not supported I'm guessing that you need to pass 'seclabel' or 'user_xattr' or some such mount option to guestmount to support this. I notice you can pass such options through the -m option to guestmount, but not -i which we need to use. Is there a way to support -i and a subsequent chcon(1)? cheers, Pádraig.
