Device nodes not created after update

[Morten Bo Johansen <mortenbo@xxxxxxxxxxx>]

Hi,

I am on Arch Linux and strangely after updating e.g. the kernel, device
nodes (/dev/sdb1, etc.) for removable devices such as usb disks are no
longer created when I plug in the disk. If I reboot, they are created again.

Is there a systemd command I can run after upgrading, so the device nodes
are created without me having to reboot?

Thanks,
Morten
