Fix issues of lazy install of login-inner

Browse source 
If initalisation is done, a new session would result in a reinit as
login-inner is not installed. The file /etc/UNINTIALISED helps to
prevent this from happening.

The same applies to any logic like home-manager sourcing which would
only take effect after restarting the app.
