8.2. Software upgrades
Software upgrades means overwriting old package files which are already installed on your system by newer ones. Notice, you have to
make sure the to-be-upgrade application files are not in-use by active clients, otherwise unstable situation can occur.
8.2.1. Upgrading shared libraries
Upgrading shared libraries can be dangerous. Since shared libraries are used by one or more applications. For example, the
glibc system library is almost used by all applications in your system. It is suggested you reboot all clients
after shared libraries upgrades, otherwise your system may behave unstable.
