TMUX or not TMUX, that is the question

This seems to be a difficult question. We had the pleasure to find out that TMUX is introduced and forced into SL1 from 12.2.1 and later, and then we were even more happy that 12.3.4 introduced that TMUX is not anymore forced, but can be enabled at will.

The 12.3.4 is again without TMUX by default, but the session handling is even more stricter with timeouts. The timeout is now handled differently, so even if you are running for example "tail -f ..." command for debugging something and the screen is updated constantly the session will be killed if you are not pressing any keys during 15min.

TMUX has its own good and bad features and we are learning them hard way. In multiadmin environments when TMUX enabled it will always be a surprise into what session you hop into when opening a new session.

Found in one KB and in 12.3.4 that there is a new section [OS_HARDENING] available in silo.conf, not much documentation about that though. Would be interesting to know what can be tuned there.
