I kept hearig from people that LINUX updated - anytime - without restarts or reboots. This was something AIX could not do. Well, neither was accurate. I had paid attention in the past - and I saw the restarts of sub-systems.

I am happy to report that LINUx is being more honest about the "disruption" of services due to some updates.

  x There are services installed on your system which need to be restarted when certain libraries, such as libpam, libc, and      x
  x libssl, are upgraded. Since these restarts may cause interruptions of service for the system, you will normally be prompted   x
  x on each upgrade for the list of services you wish to restart.  You can choose this option to avoid being prompted; instead,   x
  x all necessary restarts will be done for you automatically so you can avoid being asked questions on each library upgrade.     x
