For sure, everything that is significant nodm should set it (and the bug
here is that nodm does not set $SHELL, which is significant).

The question is what to do with the rest: leave them or clear them?

Leave them means potentially leaving rubbish around (especially in the
case of root restarting nodm manually). On the other hand, does it mean
leaving around some useful variables set during the boot process that we
do not know about?

Clearing them means that restarting nodm manually yields the same
session as when it starts by itself at boot, which is desirable.
However, if there are variables that we do not know of that are set
during boot, we end up getting rid of them.

Implementation is simple both ways: I cannot decide which one is better,
though.


Ciao,

Enrico
