>Description:
I've made a directory for jailing, called /home/jail/base. I've nullfs'ed this to
/home/jail/test/base and symlinked a number of directories from it making a world
to jail into. Doing du -ks /home/jail/test gives:

su-2.05b# du -ks /home/jail/tek
du: fts_read: No such file or directory

Doing du -ks /home/jail/tek/* gives a correct listing, however

>How-To-Repeat:
If this doesn't lead to a correct repeating, I can repeat it here, so mail
me for testing :)
