Confirmed. This means that the path structure differs depending on the
number of elements of the array... :-/

And this notation is only valid for "leaf". As "higher" level arrays like
/etc/host/ use another notation even with only one element in the array:

augtool> print /files/etc/hosts
/files/etc/hosts
/files/etc/hosts/1
/files/etc/hosts/1/ipaddr = "127.0.0.1"
/files/etc/hosts/1/canonical = "localhost"
/files/etc/hosts/1/alias = "localhost"

Actually, that's how I represent them in Config::Model::OpenSsh. I
think the end user will be more interested in configuring Subsystem by
names instead of dealing with "artificial" numbers. This gives a
structure like:

 Subsystem:sftp=/usr/lib/openssh/sftp-server
 Subsystem:internal-sftp=/usr/lib/openssh/sftp-server

and you can set them from command line using this subsystem name
oriented notation:

 $ config-edit -model Sshd  Subsystem:sftp=/usr/lib/openssh/sftp-server \
   Subsystem:internal-sftp=/usr/lib/openssh/sftp-server

But that's also another problem ;-)
