Wouldn't it be better to simply disable compiling/using lvmetad on such systems ?

HEAD of 2.03 already dropped lvmetad anyway.

Do you need any sort of autoactivation in ramdisk ?

There is probably higher complexity.

pvscan was not moved into systemd service just for fun - there have been at 
least 2 major mandatory points why  'pvscan' with autoactivation MUST NOT be 
executed from udev rule directly (udev timeout)

So the proposed patch must be NAC-ked as it is - as it probably causing way 
more troubles then it solves.
