Riki, if you hack my TV I will call XCP my "appliance"!

Sorry I wasn't completely clear.
The reason why the use of /etc/passwd vs /etc/shadow is
non-consequential is that XCP is a single user machine where all
access is via UID 0.
As such UNIX file permissions are effectively useless. For all intents
and purposes 700 = 777 if you are always root and everything is owned
by root yes?
Does this further clarify why changing to /etc/shadow would be of no

No, if anything, it makes even less sense. If all the daemons are running as root, then the excuse that was put forward, that using shadow would stop the necessary daemons from being able to perform their synchronisation properly, is moot. In the situation I am talking about here, root is often not used as a super-user. Although it would be understood that in the requirement of XCP this might be bypassed, the easy-access by keeping the password in a world-readable file would not be acceptable.

Is it possible to stop looking at the XCP as the unix-like distribution based on centos linux and start to look at it as a appliance. Are you guys evaluationg your microwave oven, fridge, NAS, set-top box and your smart TV?
