Description Harald Schmalzbauer 2010-04-16 08:20:00 UTC
	There are several LORs with unionfs reported. One seems to lead to a hard lock.
For example I used to mount /usr/local/etc via unionfs over read-only unerlaying ufs.
There are reproducably hanging processes with status D+ ofter a short time.
This used to work with FreeBSD-7, but also causes problems on -current (see kern/141950)

How-To-Repeat: 	mount_unionfs /somedir/anotherdir /usr/local/etc and try starting lighttpd
with php-fastcgi for example.
mount_unionfs /somedir /root while / is readonly. Su will hang and force yout to hard reset the machine.
