>Environment:

	2.2.6-STABLE as of April 4, 1998.

>Description:

	ktrace writing to a file over NFS plain doesn't work.  The ktrace.out
	is constantly reset to 0 bytes.

	Worse, when I tried ktrace -C then ktrace -p again (still logging
	over NFS), the machine panic'd.  I don't have the panic output.

	cd'ing /tmp first (local filesystem) then ktracing does the right
	thing.

>How-To-Repeat:

	do ktrace with current directory on NFS mount.

>Fix:
