>Release:        FreeBSD 4.4-RELEASE i386
>Organization:
no org
>Environment:

	Three systems:
		dyn:  FreeBSD 4.2-RELEASE
			nfs client from "srv"
			nfs server to   "disp"
		disp: FreeBSD 4.4-RELEASE
			nfs client from "dyn"
		srv:  FreeBSD 2.2.1-RELEASE
			nfs server to "dyn"

	The same thing happens when exchanging the 4.2- and 4.4-
	RELEASE systems. -> This bug is still present in 4.4

>Description:

	At the moment when mounting from "srv" onto "dyn" 
	into a directory in the filesystem that is exported to "disp",
	"disp" gets a read error from the nfs ("i/o error" or
	"permission denied").
	(The export from "dyn" to "disp" has option "-alldirs" set.)

>How-To-Repeat:

	see description above.

>Fix:

	Puuuh, not yet.
