You are taking my quote out of context. I didn't change anything on the 
server to make the script start working. I updated the script to see if 
it would work after trying Greg's test. There were no program or setting 
updates on the server, and certainly nothing that updated dash. This is 
Debian/Stable we're talking about, after all.

Since it is a file server, there probably were changes to the files on 
its shares, but I'd hardly count that as an "update". Similarly, it was 
running cron jobs for backups and virus scans (unsuccessfully) but again 
I wouldn't call those "updates".
