If the nisdomain is not responding, I would claim the system should still boot, so I would think that is a bug.  But if systemd/pam is not timing out on the non-responding nisdomain or the timeout is too high then I would think that might screw up a significant part of the system because lookups of passwd/hosts/group access may not work, depending on where else nis pieces are setup.  I would think if file was first and there is a valid entry in the file that it should not go to nisdomain, but that may depend on what the order is in /etc/nsswitch.conf.

I was just updating a Fedora35 server to Fedora37, using a full reinstall and then copying configuration files from the old system. The system failed to boot with lots of strange issues with systemd. It started with console messages like: [ TIME ] Timeout waiting for device dev-zram0.device - /dev/zram0. Some further issues with zram, followed by some other services starting fine then the system gets in a loop: [ FAILED] Failed to start systemd-udevd.service - ... [ FAILED] Failed to start systemd-oomd.service - ... None of this was logged in /var/log/messages. After some tracking down on a VM, I found the issue was somehow caused by having "NISDOMAIN=kingnet" in the file /etc/sysconfig/network. This came from an old client configuration ,setting the NIS domain. This was not actually needed on the server and in fact not needed on the clients now as the DHCP does this on our systems, it was a hangback from 20 years or so. I have no idea why this has caused the boot fail though, I thought I'd mention it in case anyone else sees it. I will report it as a "bug" against systemd although I'm not sure it is really a systemd issue or really a bug at all, but a bit nasty as the system fails to boot.
