Distributions apparently only compile a subset of TPM2 drivers into the kernel. For those not compiled it but provided as kmod we need a synchronization point: we must wait before the first TPM2 interaction until the driver is available and accessible. This adds a tpm2.target unit as such a synchronization point. It's ordered after /dev/tpmrm0, and is pulled in by a generator whenever we detect that the kernel reported a TPM2 to exist but we have no device for it yet. This should solve the issue, but might create problems: if there are TPM devices supported by firmware that we don't have Linux drivers for we'll hang for a bit. Hence let's add a kernel cmdline switch to disable (or alternatively force) this logic. Fixes: #30164 |

Files in this directory contain configuration for systemd-udevd.service, a daemon that manages symlinks to device nodes, permissions of devices nodes, emits device events for userspace, and renames network interfaces. See man:udev(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of service itself. Use 'systemd-analyze cat-config udev/rules.d' to display the effective config.
