get chain of users created by chaining su calls

While administrating a linux server (a Debian server, for instance), I often switch users. Sometimes, I will chain multiple user switches together:

aluriak$ sudo -s
root$ […]
root$ su aluriak
aluriak$ […]
aluriak$ su db
db$ […]
db$ 
aluriak$ su front
front$ […]

Is there any way for me to get the "chain of users" I created that way? In the upper example, that hypothetical utility would output something along the lines of front aluriak root aluriak, because I am the front user, that logged in from aluriak user, that himself logged in from root account, that itself was reached from the aluriak account.
