  RP> Xpath should allow to parse this easily (as if it was only one node) imo.

Thanks. What's Xpath? Is it the same as this one:

http://www.w3.org/TR/xpath20/

?

How is it supposed to be interfaced to augeas?

  RP> Nice. This doesn't seem to support all dhclient conf options though. In my
  RP> dhclient.conf, I have stuff like

  RP> alias {
  RP>   interface "eth0";
  RP>   fixed-address 192.5.5.213;
  RP>   option subnet-mask 255.255.255.255;
  RP> }

Yes, I still have to implement block-statements like the one above. By
now only one-line statements are supported.

Ciao,
