File::Flat implements a flat file system. A flat file system is a file system in which directories do not exist. It provides an abstraction over any normal file system which makes it appear as if directories do not exist. In effect, it will automatically create directories as needed. This is create for things like install scripts and such, as you never need to worry about the existence of directories, just write to a file, no matter where it is.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
