On my previous SVR3-system the spooler was also used as a job-queue; a "printer" got a comma-delimited file, and produced a file in word-format for mailmerge in another directory. I once wanted to check every printer to see if they worked, so I made a small script which did echo $printer|lp -d$printer This "printer" did a chmod on /$inputfile. As there wasn't any input file when lp got its input from stdin, it chmod / instead, so as in your case, only root could log in. 4 hours of downtime, and a bill from support, because I did the damage. I think I succeded to brush it off on the company who made the spooler...
