- First, port everything using `/var/lock` or `/run/lock` to lock something that has an obvious `flock` target (e.g. a serial device), one-by-one, to use `flock` *and*` a lockfile, silently ignoring permission errors iff it successfully acquired the `flock`.
We can do this on Linux-with-udev, because /dev is guaranteed to support flock(). This might break on some embedded devices with pre-created device nodes (for faster boot), and on NFS-root, but everyone using one of these has left Debian years ago.
- Second, when everything has been ported *and* we've been through some transition period (using package dependencies in Debian and allowing some time for third-party sotware), we let software start deleting the lockfile code.
The actual code will probably need to remain because we can't make decisions for non-Linux here. We might want to disable it.
