 This is a bug in mount(8). The mountfs() function calls several
 functions which may cause mount(8) to exit with error status. This
 breaks the "failok" functionality.
 
 I tried to remove most exit points in the following patch. Changing
 checkpath() isn't trivial because also file system specific mount
 commands use the function.

 Please report back if you are able to test the patch.
