[Box Backup] What I miss on boxbackup

[Thomas Glanzmann]

Hello,
this is my personal feature list which is missing from boxbackup for my
current usage scenario. Maybe I will start to submit a few patches.

        (x) Stay on same filesystem
        ( ) Don't backup bigger files
        ( ) IPv6 support
        ( ) readline tab completion for text interface
        ( ) double '//' bug
        ( ) handle device files, unix sockets and named pipes

I use boxbackup-0.9 to backup the root filesystems of three machines
which works quiet well. I like it better every day. :-)

        Thomas

This patch tells bbackupd to stay on the same filesystem. But it doesn't
touch bbackupclient. So it shouldn't be comitted that way.
