Summary0002641: initrd can't boot and failed at switch-root of systemd
DescriptionWhen using initrd to boot RockyLinux, it always failed at switch-root service of systemd, then hung and can't boot into the real rootfs.
Steps To Reproduce1. Set up a iscsi target to store the rootfs for iscsiboot.
2. Use dracut to create an initrd from rootfs directory.
    /usr/bin/dracut -v -m "base network iscsi nfs systemd-initrd systemd-networkd systemd-udevd systemd-modules-load systemd-journald systemd-integritysetup" --hostonly-mode "strict" --hostonly-nics "virtio-net" --no-early-microcode --install "/usr/bin/ping" --add-drivers "nfs nfsv4" --force-drivers "mfd-core configfs" --filesystem "ext4 xfs" ./initrd.img 5.10.45_xxx
3. Boot system with initrd. and Kernel command line is "systemd.log_level=debug systemd.log_target=console ip=192.168.0.2::192.168.0.1:255.255.255.0::eth0:off root=iscsi:192.168.0.1::::iqn.e2000:acx in
itrdmem=0x440c000000,0x8000000 acpi=force rd.neednet=1"
4. boot failed and showed log:
