Comment 2 for bug 223636

These questions definitely need further investigation. :-)

First of all we need to know
 * which backends are able to recover from a temporary connection drop and
 * which backends are able to recover from a permanent connection drop with IP address change.

According to my experiences sftp backend recovers quite well from temporary drops but it fails to recover from IP address change. (since it is using ssh over TCP behind the scenes)

My very new idea: in if-up we should somehow detect whether or not the IP address has changed since the last connection and we should unmount remote shares only if it has changed.

Or we should provide a configuration option to distinct "roaming laptop mode" from "always connected desktop mode".
