Comment 3 for bug 346285

I was halfway through typing up a reply earlier today, but couldn't word it right as I was distracted - basically, I was going to say what prismatic said regarding ubuntu automounting external usb.

while sbackup had this option, it did not work properly as the gui which should have set the config value in the etc/sbackup.conf was not doing so it was as if it defaulted to 0, because even if you manually edited the file and then changed something in gui, it would revert back.

I've written a more complete post (rant) regarding this behaviour - granted it's on sbackup, but related to the current nssbackup behaviour - http://blog.rvdavid.net/30-gb-root-partition-full-how/
