[SOLVED] Systemd is updated, Linux kernel not, mkinitcpio hook started

Why if systemd is updated but Linux kernel(s) is/are not, mkinitcpio hook is started and creates kernel image(s) when it is not needed?

There are systemd files in the initramfs, so it *is* needed.

Ok, found it, not many, but they are:

-rwxr-xr-x  0 0      0     4319928 sty  1  1970 usr/lib/systemd/libsystemd-shared-255.2-1.so
lrwxrwxrwx  0 0      0          16 sty  1  1970 usr/lib/systemd/systemd-udevd -> /usr/bin/udevadm

It's more than that, even without the systemd hook. Grepping for 'systemd' doesn't work, not all files have that word in the filename.

Some not obvious examples?

See `comm -12 <(lsinitcpio /boot/initramfs-linux.img | sed 's|^|/|') <(pacman -Qql systemd)`

Or just read the udev or systemd hooks.
