Dear Damien,

Thanks for your response!

I didn't really care about how to name this.  All I did was noting
that the flag is stored in a C variable "no_shell", which I just
translated to camel case.

So I assume that we should rename that C variable as well?

I also don't think that reusing RemoteCommand is a good idea.  This
would add unnecessary entaglement of mostly-unrelated options, and as
such increase the risk of accidentally introducing bugs.

I'd prefer to rename NoShell to NoSession, and perhaps to do the same
for the internal variable names for consistency.  Then, we would have
a one-to-one match of command line and configuration file, which is
IMHO the least surprise for users already familiar with "-N" and "-s".

However, I'm not opposed to introduce "SessionType=none/subsystem", in
case you like me to implement it that way.

How should we proceed from here?  Which variant should I implement?


Best regards,
Volker
