"does not support multiple filesystems/root trees." I just tried the experiment on Ubuntu 14.04 and that statement does not appear to be true. If I create a file on a mounted non-root filesystem then run updatedb followed by locate with a pattern matching that filename I get the file's path. There are a couple of things that could be preventing this in /etc/updatedb.conf. Make sure the mounted filesystem isn't excluded by PRUNEPATHS or PRUNEFS. Also I'm not clear on what PRUNE_BIND_MOUNTS does but my guess is that if set to yes it would exclude nfs mounted filesystems.
