I don't want to put words in Greg's mouth, but if you check the code for udevd at this moment you can see a lot of use of utility headers that are not really appropriate for a libudev: https://github.com/systemd/systemd/blob/c54cfef3968613f9e86e...

Expanding udev's library would probably end up a decent size library of other functionality, I don't think there is any good way around needing this. This is not code that could be deleted from systemd if it was separated. The way eudev has handled it is by doing what you describe and copying those shared functions out from systemd: https://github.com/gentoo/eudev/tree/34b2037d379e33f1cf79a34...

The result of that being there are two copies of the same shared code floating around, which is what they were trying to avoid.

That's fair.

Why not? You could make a library out of those utility functions and use it from both systemd and udev (without having to include most of libsystemd which doesn't seem useful for udev).

I don't have a quote handy, but systemd maintainers have previously said they are not interested in also maintaining a giant public API of utility functions, on top of everything else.
