Lock files using the flock() call. If the file to be locked does not exist, then the file is created. If the file was created then it will be removed when it is unlocked assuming it's still an empty file. Locks can be created by new'ing a File::Flock object. Such locks are automatically removed when the object goes out of scope. The unlock() method may also be used. lock_rename() is used to tell File::Flock when a file has been renamed (and thus the internal locking data that is stored based on the filename should be moved to a new name). unlock() the new name rather than the original name. Locks are released on process exit when the process that created the lock exits. Subprocesses that exit do not remove locks. Use forget_locks() or POSIX::_exit() to prevent unlocking on process exit.
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.
