apt-get / aptitude [g]libc update not to prompt for restart and not restart

[Mihamina RAKOTOMANDIMBY <mihamina.rakotomandimby@rktmb.org>]

Hi all

I'm going to massively upgrade some ghost-vulnerable machines.

Digging into the apt-get or aptitude documentation, I miss the right option in order to make it upgrade libc & libc-bin without restarting the services and without asking what to do.

Would you know the right option?

Thank you.
