> Hm...does Jessie not set $UID?

You have a typo in there.  It's $UI, no D.  (or was a while ago.  I couldn't 
figure out what it was trying to do.)

It's not in my environment, but $UID works.  Is that something special with 
bash?

On Fedora:
[murray at hgm ~]$ sudo echo $UID
1000
[murray at hgm ~]$ sudo su
[root at hgm murray]# echo $UID
0
[root at hgm murray]#

FreeBSD, as root, running csh
root at ted2:/home/murray # echo $UID
UID: Undefined variable.
root at ted2:/home/murray #
