"Of course, to do this you sacrifice some disk space, because the statically linked executable includes a copy of the shared libraries that it needs, but in these days of terabyte disks the space consideration is less important than the security one. Consider what happens if your executables are dynamically linked to a shared library, say libfoo, and there is a security update to libfoo. When your applications are dynamically linked you can just update the shared copy of libfoo and your applications will no longer be vulnerable to the security issue in the older libfoo. If on the other hand you have a statically linked executable, it will still include and use its own private copy of the old libfoo. You'll have to recreate the statically linked executable to get the newer libfoo and security update.
"Still, there are times when you want to take a daemon you compiled on a Fedora machine and run it on your openSUSE machine without having to recompile it and all its dependencies. Sometimes you just want it to execute now and can rebuild it later if desired. Of course, the machine you copy the executable from and the one on which you want to run it must have the same architecture."
