after kernel-update: no directory /dev/seral

[ulihueck]

Hi,
yesterday I updated my pve using the web-ui.
After the update the system told me to execute

echo 'grub-efi-amd64 grub2/force_efi_extra_removable boolean true' | debconf-set-selections -v -u

and then

apt install --reinstall grub-efi-amd64

Everything ran without errors.
But my homeassistant installation claims, there is no usb-device in /dev/serial/by-id/usb-dresden_elektronik_ConBee_III_DE03
Reason: there is no directory /dev/serial anymore.
Also there is no device called ttyUSB0
But homeassistant proposes this device in the settings. It has also a directory /dev/serial/by-id/.
How can I get the directory "/dev/serial/by-id" back in pve?

where is home assistant running? on the host, in a container, ..? this sounds like you might have accidentally unmounted /dev somehow, a reboot should fix that..
