[arch-general] [arch-dev-public] Mkinitcpio replacement with Dracut

I've come across a possible issue which related to usb keyboard/mouse

I notice that booting using dracut initramfs with kernel 5.2-rc2 that as
soon as it boots it shows on the console: stopping job udev Kernel
Device Manager with red spinner.

This times out and boot continues fine - once the system has booted I
check the boot log and included interesting part of logs below. Keyboard
and mouse are both working and the relevant hid modules are loaded fine
- and xinput shows all looking normal.

Interesingly, using mkinitcpio initrd with same 5.2 kernel- the system
comes up with no keyboard or mouse (it uses logitech wireless
kbd/mouse). The hid_logitech modules seem not to have been loaded at
all. So something in the newer kernel is leading to this issue but
dracut manages to pull through anyway while mkinitcpio does not.

Obviously anyone experiencing this might be quite taken aback.

Also, everythign works fine with 5.1.5 kernel with both dracut and
mkinitcpio. the hid modules are all fine for that test case.

udev is a bit of a mystery to me - but thought I'd best mention the problem.
