Thats very much specific to boxes code.

if app is supposed to provide the avatar, we don't want these. I
propose the following changes:

* Rename Avatar to AvatarInfo and install_script_get/set_avatar accordingly.
* Document install_script_get_avatar_info a bit so the flow of
information is clear
* Dont assume in the desktop profile that app provided the value of
avatar-disk (its currently done for fedora at least)
* Keep install_script_set_avatar_info and avatar_info_new internal
(apps are not supposed to use those so they better not be exposed to
them)
* Add
  * the missing method to set a value for avatar disk config
  * config parameter to specify avatar filename/path. In fedora.xml,
you can then replace:

cp /mnt/unattended-media/<xsl:value-of select="config/user-login"/>
/var/lib/AccountsService/icons/

by

cp /mnt/unattended-media/<xsl:value-of
select="config/avatar-filename"/>
/var/lib/AccountsService/icons/<xsl:value-of
select="config/user-login"/>

Similarly for other OSs.
