[systemd-devel] Device nodes not created after update

[Mantas Mikulėnas]

Device nodes in /dev are created directly by the kernel. If they're
missing, that most likely means you don't have the *kernel drivers*
(modules) for that type of USB device – e.g. because you're still running
kernel 6.12.x so it is trying to load 'USB storage' modules from
/lib/modules/6.12.x, but of course you no longer have a /lib/modules/6.12.x
as you upgraded the whole package to 6.13.y instead.

For Arch, install the "kernel-modules-hook" package so that it retains a
copy of the running kernel's modules even after an upgrade.
