Problem description:

Bug-ID 1078206
--------------

	Problem with recursive mounts

Bug-ID 1055565
--------------

Automounter sometimes fails to do a mount.  Get the messages

        nfscast: select: Invalid argument
        trymany: servers not responding: RPC: Unable to receive

The invalid argument to select is due to a negative timeout being
supplied to select().


Bug 1038308:
------------
	In 4.1, the automounter sets up a different symbolic link
        5 min. after the first access. This happens if there are
        multiple locations for the same mount in the auto mount
        map entry, and those locations don't share the same subdir.

Bug 1048875
-----------

	The automounter forks due to rpc.rexd.  This problem
	is usually seen when using the on command.  The automounter
	will complain it cannot find /etc/mtab.

Bug 1044048
-----------

	Automounter consumes a steady, increasing percentage of memory.
	Coinciding with this is the consumption of swap space as well.

Bug 1083225:
------------

        If an entry is removed from /etc/mtab while the automounter
        daemon is reading it, it is possible for the automounter to
        get into a state where it will loop forever, printing
        "WARNING: /etc/mtab: line <number>: bad entry" on the console
        and hang the server.

Bug 1106249:
------------
        Automount behaves strangely after inserts a 28th
	server to one mount point in /etc/auto.direct.
	The reason for this is automount only support up to 20 servers 
	for 1 mount point on 4.x.    This patch changes this limitation from 
	20 to 128.   In Solaris 2.0, there will be no limitation on this.
