I'm guessing one can reconstruct your permissions as follows:
$ cd /tmp
$ mkdir nw
$ setfacl -m g:Users:rwx nw
$ chmod a-rwx nw
$ ls -ld nw
d---------+ 2 igor root 0 Dec 18 10:08 nw/
$ touch nw/foo
$ ls -l nw/foo
-rw------- 1 igor root 0 Dec 18 10:08 nw/foo
$ if [ -w nw ]; then echo "Yes"; else echo "No"; fi
One solution is, of course, "chmod u+rwx /tmp". The other is to change
rebaseall to try creating a file anyway and checking the result.
There was some talk of changing coreutils to use "access" for testing
permissions, which would probably solve this as well. However, even if I
use "/bin/test -w nw", I get a "No". Has this change ever happened? If
it ever does, bash will also need to be rebuilt so that its builtins use
the same interface. It helps that both have the same maintainer.
