I think the best solution is for Puppet to install this script on our shell nodes as /usr/local/bin/df:
#!/bin/sh
exec df -x fuse "$@"
This general issue consistently comes up in bug reports and the consensus is that the onus is on df to be smarter.
Obviously my solution isn't perfect (it might not help people who modify $PATH) but I think it solves our immediate "bad first impression" problem with an appropriate amount of effort.
- Status changed from New to Resolved

I asked for feedback on IRC and Peter and Tim both supported this approach. Looking at our system configuration, I found an even better solution: we have a shell file that gets sourced for all interactive sessions to help set up Arvados environment. I added code here to alias df as described. This is a better fit because it means it's more likely to help users (e.g., not thwarted by $PATH changes), and less likely to interfere with init scripts or other noninteractive users of df.
Reviewed and approved by Ward, and pushed to our system configuration.
