dhcpcd never discovers any interface when started before mdev

[git-bruh]

It's possible that mdev might start after dhcpcd, so dhcpcd stops looking for new interfaces altogether and doesn't output anything after this:

no such user dhcpcd
dhcpcd-9.4.1 starting
dev: loaded udev
DUID 00:01:00:01:2a:93:78:3a:d0:37:45:47:f3:16
no valid interfaces found
no interfaces have a carrier

Restarting dhcpcd makes it work properly till shutdown:

no such user dhcpcd
dhcpcd-9.4.1 starting
dev: loaded udev
DUID 00:01:00:01:2a:93:78:3a:d0:37:45:47:f3:16
no interfaces have a carrier
wlan0: waiting for carrier
wlan0: carrier acquired
wlan0: IAID 45:47:f3:16
wlan0: rebinding lease of 192.168.29.156
wlan0: probing address 192.168.29.156/24
wlan0: leased 192.168.29.156 for 3599 seconds
wlan0: adding route to 192.168.29.0/24
wlan0: adding default route via 192.168.29.227

I guess a better title would be "hotplug not working with dhcpcd" since the same happens if you replug a device: (no more output even after replug)

wlan0: carrier lost
wlan0: deleting route to 192.168.29.0/24
wlan0: deleting default route via 192.168.29.227

Try to build dhcpcd without udev support.

[git-bruh]

It works fine without it -- I guess that answers why it sometimes works when built in fresh install

wlan0: carrier lost
wlan0: deleting route to 192.168.48.0/24
wlan0: deleting default route via 192.168.48.80
wlan0: removing interface
wlan0: waiting for carrier
wlan0: carrier acquired
wlan0: IAID 45:47:f3:16
wlan0: rebinding lease of 192.168.48.156

Any reason not to disable udev support in repo?

Feel free to disable it, nothing shall break. Those who uses udev can re-enable it if needed.
