Summary:                    "mount -t auto " broken
Description: 
"mount -t auto" is broken. Mount returns the error message "no such device"
.
Not specifying "-t auto" at all or specifying the file system, i.e. "-t
ext2" works.

The cause is that the standard C librar getmntent will return "auto" as
the filesystem type, and the mount.c code incorrectly checks for a NULL
string:

if (fsType || ...

Should be:

if (strcmp(fsType, "auto") || ...

Trivial patch attached.
