Also, before that, we will need a solution to the generators issue (#992554 comment #25 and below).
Not only generators. For systemd we have to consider /lib/systemd/system-generators/ (24 packages) /lib/systemd/system-shutdown/ (6 packages) /lib/systemd/system-sleep/ (10 packages) /lib/systemd/system-preset/ (6 packages) /lib/systemd/network/ (1 package)systemd does not support reading scripts/files from a /usr/lib counterpart and we'd have to patch various places in systemd to allow that. Those patches should be simple though.
For udev, it's a bit trickier.While udev supports reading udev .rules files from /lib/udev/rules.d and /usr/lib/udev/rules.d, udev allows to run programs via RUN+= or IMPORT{program}=
If not specified with a full path, it will look up the binary in /lib/udev There are quite a few packages which hard-code a full path, like e.g.90-libgpod.rules:ACTION=="add|change", SUBSYSTEM=="usb", ATTR{idVendor}=="05ac", ATTR{idProduct}=="129[0-9a]", IMPORT{program}+="/lib/udev/iphone-set-info"
Moving everything from /lib/udev to /usr/lib/udev would break that reference.
Then there are also quite a few .rules files which don't hard-code the full path. For those we'd have to patch udev to lookup the binaries in /lib/udev and /usr/lib/udev.
Not quite sure, how we'd coordinate that. Maybe only automatically move the .rules files and then file bugs against packages shipping helpers in /lib/udev to do the migration manually (by moving the helper to /usr/lib/udev and updating the .rules files accordingly).
A rough estimation suggests that this affects 60+ packages.# apt-file search -x ^/lib/udev/ | grep -v rules.d | grep -v hwdb | grep -v rc_keymaps | grep -v ^udev: | grep -v ^systemd: | cut -f2 -d':'
