>Description:

`make release' fails at creating a memory disk for mfsroot in
release.9 target. Although the md node was actually created,
immediate `test -c' doesn't pass.

>How-To-Repeat:
	
In a chrooted environment for `make release'

# make release.9
cp /R/stage/trees/base/etc/disktab /etc

*** Error code 1

Stop in /usr/src/release.

>Fix:

Adding a short pause after creating the md node for mfsroot
solved the problem for my environment.
