Maybe this bit of info will help:

v+
bing@clubber:~$ fsysopts /tmp
/hurd/ext2fs.static --writable --no-inherit-dir-group
--store-type=typed device:hd0s1
bing@clubber:~$ ls -ld /tmp
drwxrwxrwt 9 root root 12288 Feb 19 18:07 /tmp
v-

My guess is that --no-inherit-dir-group is probably the culprit, but I
can't remember exactly why.
