* there is nothing to warn about here :)
$ systemctl stop systemd-udevd.service systemd-udevd-kernel.socket systemd-udevd-control.socket
Warning: Stopping systemd-udevd.service, but it can still be activated by:
systemd-udevd-control.socket

* kill /etc/timezone handling entirely? What does it provide?

$ ls -l /etc/localtime; cat /etc/timezone
lrwxrwxrwx 1 root root 33 Jul 27 09:55 /etc/localtime -> /usr/share/zoneinfo/Europe/Berlin
Europe/Berlin
- systemd enforces /usr to be available at bootup, so we can
enforce the use of the symlink
* check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
* swap units that are activated by one name but shown in the kernel under another are semi-broken
