Yes I have. But it is was on a Apollo system running the Aegis operatingsystem. Still one of the most fancy systems I ever worked
with... But then came HP and took over Apollo systems.

But the trick was there was a super-super user called locksmith. This user had access to everything. You could not lockout locksmith
from any file. Root was just a user who was under control of the acl. Basicly one could make every user sysadmin just by placing it
in the right group. If I remember well locksmith wasn't in the password or shadow file either, but I am not sure here. For making
backups you had to add the cpio-user to all the files were access was needed.
System backups were made by locksmith.
