However, a -STABLE or -CURRENT FreeBSD system will need /usr/src to apply any security advisories or errata (as happened recently, re: OpenSSL). Unlike -RELEASE branches, -STABLE and -CURRENT don't get updates via freebsd-update. > > Also, it's handy to have /usr/src and rebuild if ever there is a feature MFC'd that you'd like to have available on your -STABLE system (e.g., the bhyve support for AMD processors that was MFC'd not so long ago).

Also, nvidia, VirtualBox and some other packages contains kernel modules, which require a kernel source code and your setup might be affected by more updates of those ports than the system is affected by security erratas.
