+Hmm, running the commands in the pipeline by hand, I am now noticing that the
+file command part of it leaves an exit status of 1.  With this in the script:
+set -o pipefail
+
+That would make the whole pipeline exit with 1, so there's the problem.
+
+The last file that file runs on is /etc/rc.d/init.d/webmin, which it reports
+as POSIX shell script, ASCII text executable.
+
+I don't know why it's exiting with a non-zero exit status.
+
+find strikes again!
