Comment 19 for bug 1843036

I also tested the test package, 5.7.3+dfsg-1.8ubuntu3.2+testpkg20190906b3, in a direct-mapped autofs environment that was the basis for the fix that caused this regression.

The test package does fix the original autofs "mount everything" issue and allows for snmpwalk to monitor the mounted disks as well.

I even tested it with a single autofs directory mounted and it worked with that as well.
