I wonder what other existing programs Will Systemd attempt to replace in the future.
My bet is /bin/sh, maybe they went further to replace the entire POSIX utilities.

It will come with `filectl` for all your file operations, so you will no longer need `cd`, `pwd`, `touch`, `rm`, `mkdir`, `cat`, `grep`, `find`, etc. Instead you do everything through `filectl` commands.
This will deprecate many commands from GNU coreutils, which is a good thing because replacing things is always good.
Then, since programs are just files, and filesystem will be part of systemd, any program you want to use will obviously have to go through systemd as well, meaning they will need to be a service unit of type `oneshot`, because this way we keep everything well integrated together.
Don't worry tho, you only write the unit files once and they work forever. The only thing you need to remember is that, instead of `cargo build` you'll need to use `filectl exec -u cargo build` (`filectl exec -u` is only 3 words, so you don't have the right to ever complain about this tiny little change).
Anyone who doesn't like these changes is stuck in the past.
This is not as ridiculous as it sounds. Arguably, the file system is more of an exception, because it is directly exposed by the kernel. But, for example, to manage the files in a tar archive you do everything with the `tar` command and to manage a git repository you do everything with the `git` command.
