strange error

[Oliver Lehmann]

all I find out right now is, that in phase 0 everything is OK, and in phase 
in my ${chroot} only the following directories are left: 

drwxr-xr-x  3 root  wheel  512 Nov 30 11:42 compat
dr-xr-xr-x  5 root  wheel  512 Nov 30 11:37 dev
dr-xr-xr-x  1 root  wheel    0 Nov 30 11:42 proc
drwxr-xr-x  5 root  wheel  512 Nov 30 11:42 tmp
drwxr-xr-x  4 root  wheel  512 Nov 30 11:42 usr
drwxr-xr-x  3 root  wheel  512 Nov 30 11:42 var
drwxr-xr-x  2 root  wheel  512 Nov 30 11:42 work 

everything else is gone.... investigating now why...
btw. I'm using tinderbox HEAD
