Fedora Cloud 42 agetty segfaults

Running the Fedora Cloud 42 image in proxmox (I haven’t tested other hypervisors) results in the following errors from the serial-getty service:

Apr 17 19:10:43 type-null agetty[1021]: could not get terminal name: -22

If some here could help me with this, it would be greatly appreciated.

Looks like it’s failing to detect the terminal name (possibly because your VM doesn’t have a serial console?) and then the next bit of code attempts to string compare on the name without checking that the name lookup failed.

Seems to already be fixed upstream at agetty: fix stdin conversion to tty name by karelzak · Pull Request #3425 · util-linux/util-linux · GitHub.
