   Note:  mount_hsfs has a new option now:
          notraildot
                    File names on High Sierra file  systems  con-
                    sist  of  a  proper  name  and  an  extension
                    separated  by  a  '.'  (dot)  character.   By
                    default,  the  separating  dot is always con-
                    sidered part of the file's name for all  file
                    access   operations,  even  if  there  is  no
 		    extension  present.   Specifying   notraildot
                    makes it optional to specify the trailing dot
                    to access a file whose name lacks  an  exten-
                    sion.
                    Exceptions:
                         This option is effective  only  on  file
                         systems  for which Rock Ridge extensions
                         are not active, either because they  are
                         not  present  on the CD-ROM, or they are
                         explicitly ignored via the  nrr  option.
                         If  Rock  Ridge  extensions  are active,
                         hsfs quietly ignores this option.

1151636 Mounting ISO-9660 cd disp file names with the separator "." appended

(from 101785-01)

NASA is using a cdrom with a 512-byte blocksize (not 2048) on systems
running Solaris 2.2 and 2.3.  The immediate symptoms were that file
sizes and modification dates were incorrect.

More generally, when a file is requested by "name", an open/stat
would return a different file than the one requested.

The specific problem was that hsfs was generating duplicate nodeid's
and entering them into a hash table; each time a file is looked-up,
the hash-list was checked and matched the file to the wrong vnode.
